DESCARTES - Une expérience philosophique de la vérité, Denis Moreau

DESCARTES - Une expérience philosophique de la vérité, Denis Moreau

Introduction to the Topic

The speaker introduces the topic of philosophical discussions and proposes to explore the question of whether truth exists or not, drawing on Descartes' philosophy.

Exploring the Existence of Truth

  • The speaker presents their definitive answer to the question of whether truth exists or not, aiming to provide a conclusive resolution for the audience.
  • Philosophy is seen as a series of debates or conflicts between opposing viewpoints, such as the debate between free will and determinism, or empiricism versus other sources of knowledge.
  • One fundamental debate revolves around those who believe in the existence of truth and our ability to know it (dogmatists), and those who argue that truth either doesn't exist or we lack means to attain it (skeptics).
  • Dogmatists are not necessarily pejorative; they hold that one can rightfully support opinions and defend their truth.
  • Skeptics, also known as Pyrrhonists after Pyrrho, an ancient Greek philosopher, claim that truth either doesn't exist or is beyond our reach.

Descartes' Meditations

The speaker discusses Descartes' work "Meditations on First Philosophy" and its unique structure that combines theoretical propositions with intellectual exercises.

Interactive Reading Experience

  • Descartes' "Meditations on First Philosophy" differs from typical philosophical books by including both systematic propositions and exercises for readers to engage with.
  • Readers are invited to embark on an intellectual journey while reading the text, experiencing both theoretical truths and personal transformations through exercises.
  • This interactive aspect makes "Meditations" akin to modern interactive books or choose-your-own-adventure stories.

Philosophical Experience in "Meditations"

The speaker highlights the experiential nature of reading Descartes' "Meditations" and compares it to interactive books or games.

Becoming the Hero of the Text

  • "Meditations" offers readers a genuine intellectual experience, allowing them to become the heroes of the text.
  • Readers are encouraged to meditate and engage with the exercises presented in the book.
  • This philosophical experience is unique and should be undertaken seriously, as it can have psychological and intellectual implications.

Cautionary Notes on Descartes' Exercises

The speaker provides cautionary remarks regarding Descartes' exercises, emphasizing their potential psychological and intellectual risks.

Exercise with Care

  • Descartes suggests that everyone interested in philosophy should undertake his exercises at least once in their life.
  • However, these exercises should not be performed frequently due to their potentially dangerous effects on one's psyche and intellect.
  • The seriousness required for these exercises may lead to psychological and intellectual challenges if not approached with caution.

Introduction and Setting the Stage

The speaker introduces the topic of skepticism and its relation to truth. They mention that they will be examining our knowledge and beliefs, testing them against the doubts raised by skeptics.

Taking Skepticism Seriously

  • The speaker poses the question of whether there is any truth, as skeptics claim that truth does not exist.
  • They explain that they will examine our accumulated knowledge, beliefs, and opinions to distinguish between those that are doubtful and those that are certain.
  • This process is referred to as the "first meditation of Descartes," where all opinions are treated as false until proven indubitable.
  • The speaker emphasizes the importance of exaggeration in this process, considering even the most bizarre and extravagant doubts.

Three Steps of Methodical Doubt

The speaker introduces a three-step approach to methodical doubt proposed by Descartes. These steps involve identifying a domain of knowledge or beliefs, determining reasons for doubting them, and seeking new reasons for doubt if any resistance arises.

Organized Doubt

  • To doubt systematically, one must proceed in an organized manner.
  • The three-step approach involves:
  1. Identifying a domain of knowledge or beliefs.
  1. Determining reasons for doubting these beliefs.
  1. Seeking new reasons for doubt if any resistance arises.

Doubting Sensory Information

The speaker discusses how sensory information can be deceptive at times and acknowledges that some sensory perceptions can be erroneous.

Erroneous Sensory Information

  • Sensory information is often considered reliable but can sometimes be misleading.
  • Examples include optical illusions where objects appear different from reality (e.g., a straight stick appearing bent when placed in water).
  • Mirages can also create false perceptions, such as seeing an oasis in a desert where none exists.
  • In the spirit of exaggeration, all sensory information is considered false to some extent.

The Body as a Source of Doubt

The speaker acknowledges that while sensory information may be doubted, the existence of one's own body cannot be easily dismissed.

The Body's Role in Perception

  • Skeptics question whether the certainty of having a body can be trusted.
  • However, the speaker argues that for sensations to occur, there must be a body affected by various stimuli.
  • While sensory information may be doubted, the fact that one has a body collecting this information remains assured.

This summary covers only a portion of the transcript.

The Theme of Confusion between Dream and Reality

This section explores the theme of confusion between dreams and reality in movies such as Total Recall, Matrix, and Inception. It raises the question of whether we can truly distinguish between dreams and reality.

Dreams vs. Reality

  • The speaker asks if you have ever dreamed that things were happening to your body, like having wings, while lying in bed. This blurs the line between dreams and reality.
  • Sitting next to someone, you may question if it is certain that you are really there or if it could be a dream.
  • The speaker suggests that when we dream, we perceive it as reality without recognizing it as a dream. Dreams have the same level of reality as our waking experiences.
  • We are convinced of the reality of our bodies and their physical sensations. However, the speaker challenges us to consider if this could also be part of a dream.

The Dangerous Nature of Doubt

  • Doubting the certainty of our perceptions makes life complicated. For example, imagine being at home in your room when your mother tells you dinner is ready. You hesitate to believe her until you are absolutely certain it's not a dream.
  • Doubting our perceptions can lead to extreme skepticism and make us question even basic facts about our existence.

The Content of Dreams

  • Even though dreams may be considered fictional or illusory, they possess certain characteristics that do not undermine their content. For example, mathematical principles remain consistent in both dreams and wakefulness.
  • Plato's example illustrates this point: If you dream about seeing two pigeons while awake or dreaming, the mathematical truth that two plus two equals four remains unchanged.

Mathematics as a Model of Certainty

  • Philosophers, following Plato, have regarded mathematics as a model of certainty and truth that cannot be undermined by skepticism.
  • However, skeptics challenge even the certainty of mathematics, using any argument available to them.

Descartes' Dangerous Doubts

  • Descartes suggests the possibility of an evil power or deceiving demon that distorts our thoughts and perceptions. This introduces doubt even in our most certain beliefs.
  • Descartes acknowledges that this hyperbolic doubt may seem metaphysical and abstract but insists on considering it seriously.
  • It is dangerous to engage in this level of doubt as it can lead to questioning the validity of all thoughts and experiences.

Doubting the Existence of God

  • The transcript mentions doubting the existence of God but does not provide further details or arguments for this doubt.

Recapitulation: Steps in Doubt

This section summarizes the steps taken so far in exploring doubt and skepticism.

Steps in Doubt

  • The speaker suggests there is one thing left to doubt: the existence of a deceiving god. While there are good reasons to doubt God's existence, it is more difficult to question than mathematical truths.
  • The transcript does not provide further details on this topic.

New Section

The speaker reflects on the existence of God and the uncertainty surrounding our senses, body, and knowledge. The atmosphere is described as one of doubt and devastation.

Reflection on Uncertainty

  • The speaker questions the certainty of our senses, body, sciences, and mathematics.
  • Previously presumed areas of knowledge have revealed their fragility and collapsed.
  • There is a sense of impending doom in the pursuit of truth and certainty.

New Section

The speaker describes a moment of intellectual panic where they feel lost and overwhelmed by doubt. They express surprise at their inability to find solid ground.

Moment of Panic

  • The speaker experiences a deep sense of panic, feeling as if they have fallen into deep water.
  • They are unable to find support or swim to stay afloat.
  • This leads to a sinking feeling and an immersion in doubt.

New Section

The speaker reflects on losing a game played with skepticism. They describe sinking into skepticism themselves, but then experience a moment of intellectual rebellion.

Sinking into Skepticism

  • The game played with skepticism leads to defeat.
  • They sink into skepticism themselves, not the sympathetic or ironic kind encountered before.
  • However, there is a sudden rebound in the form of intellectual rebellion.

New Section

The speaker expresses a rebellious outcry against skepticism. They discuss different formulations of "cogito" (I think) that capture this revolt against doubt.

Rebellious Outcry

  • A cry of protest is directed towards skeptics and their arguments.
  • This rebellion is seen as important in contrast to different formulations of "cogito."
  • Three main formulations are mentioned: "Cogito ergo sum," "Moi je suis moi j'existe," and "Je pense donc je suis."

New Section

The speaker discusses the significance of the "cogito" and its reaction to skepticism. They argue that it offers a clear experience that contradicts extreme skepticism.

Significance of "Cogito"

  • The "cogito" is seen as a frustrated and desperate reaction to skeptical arguments.
  • It represents a defiant surge against doubt.
  • The speaker argues that extreme skepticism, claiming everything is doubtful or uncertain, contradicts the act of making such claims.

New Section

The speaker declares victory over skepticism by pushing doubt to its limits. They assert the certainty of their existence through the statement "I think therefore I am."

Victory over Skepticism

  • By fully embracing doubt, the speaker overturns skepticism on its own grounds.
  • The statement "I think therefore I am" emerges as an undeniable truth.
  • This assertion is immune to even the most extravagant suppositions of skeptics.

New Section

The speaker emphasizes the importance of taking seriously the implications of the statement "I think therefore I am." They invite listeners to consider if they are capable of thinking something true.

Taking Seriously

  • Listeners are urged to take seriously what is being asked: whether they can think something true.
  • Choosing one's preferred formulation of Descartes' statement becomes crucial in this context.
  • A minute is given for listeners to try and cast doubt on their chosen formulation.

New Section

The speaker highlights how attempting to cast doubt on the statement "I think therefore I am" only reinforces its validity. Doubting leads to affirming one's existence.

Reinforcing Validity

  • The speaker suggests that the more one tries to doubt the statement, the more it is validated.
  • Doubting requires a subject who engages in the act of doubting, thus affirming their existence.
  • Personal experience supports the validity of "I think therefore I am."

New Section

The speaker reflects on their personal experience with the "cogito" and skepticism. They find it difficult to understand complete and definitive skepticism.

Difficulty with Skepticism

  • The speaker shares their own experience with Descartes' "cogito" and doubt.
  • They express difficulty in comprehending those who embrace complete and definitive skepticism.
  • Extreme skepticism contradicts itself by claiming everything is doubtful while assuming a subject who makes such claims.

New Section

The speaker concludes by apologizing if their perspective on skepticism may upset some listeners.

Apology

  • The speaker apologizes if their views on skepticism cause any discomfort or dissatisfaction among listeners.

The Exceptional Nature of the Cogito

This section discusses the exceptional nature of the cogito and its popularity among philosophers and the general public.

The Popularity of the Cogito

  • The cogito has been widely discussed and debated by philosophers since Descartes, making it an important philosophical concept.
  • Unlike other technical philosophical statements, the cogito has become popular and well-known among the general public in France.
  • Examples of popular variations and puns on the cogito can be found in everyday conversations, songs, and even advertisements.

Challenges to the Cogito

This section explores potential challenges to the cogito, particularly from skeptics who question its validity.

Skepticism and Difficult Questions

  • Skeptics may challenge the cogito by posing difficult questions about truth and reality.
  • One such question is "What is truth?" which raises complex definitions that have long fueled debates among philosophers.
  • The classic definition of truth as correspondence between a statement and reality may not easily apply to thoughts or mental states.

The Unique Value of the Cogito

This section emphasizes that despite skepticism, the cogito holds unique value as an indubitable act of thought.

Indubitable Act of Thought

  • The cogito allows us to isolate a certain undeniable presence: an act of thought that we know to be true because we experience it firsthand.

The Nature of Definitions

This section discusses the nature of definitions and the process of defining concepts. It explores how definitions require words, which in turn need to be defined, leading to a regression process.

Defining Concepts

  • Definitions involve a regression process where words are used to define concepts, but those words also need to be defined.
  • Pascal's quote highlights that attempting to clarify words can often obscure their meaning.

The Elusiveness of Truth

This section delves into the elusiveness of truth and the challenge of defining fundamental terms that constitute thought.

Obscuring Words

  • Words like "being" and "thought" are considered fundamental elements that make thinking possible.
  • However, attempts to elucidate these terms often lead to further confusion.

The Role of "Being"

In this section, the speaker engages with individuals in the audience to explore the concept of "being" and its implications.

Engaging with Individuals

  • The speaker asks individuals about their occupation and uses verbs like "to be" in their responses.
  • By highlighting these instances, the speaker emphasizes how "being" is intertwined with our understanding and expression.

Defining Time

This section focuses on defining time and challenges associated with using language for definition purposes.

Defining Time

  • The speaker asks an individual about the duration of their speech (35 minutes) as an example.
  • By pointing out that time cannot be defined using time-related terms, it highlights the limitations of language in capturing certain concepts accurately.

The Sceptic's Game

Here, the speaker addresses skepticism and its impact on defining fundamental elements of thought.

The Sceptic's Approach

  • The sceptic exploits the difficulty in defining certain fundamental terms to create doubt and confusion.
  • However, the speaker suggests not falling into the sceptic's game and acknowledges that some aspects cannot be defined.

Three Key Observations

This section presents three key observations related to the discussion on thought and existence.

Observation 1: "I Think, Therefore I Am"

  • The speaker refers to Descartes' famous statement, "I think, therefore I am," highlighting its first-person perspective.
  • This observation emphasizes a philosophy of personal appropriation in understanding and expression.

Escaping Personal Appropriation

Here, the speaker explores ways to escape personal appropriation in philosophical discourse.

Alternative Expressions

  • The speaker suggests alternative expressions like "for thinking to occur, there must be" instead of "to think is to be."
  • By using different expressions, one can avoid being personally implicated in the definition process.

Thought Experiment: Thinking Someone Else's Thoughts

This section introduces a thought experiment involving someone else's thoughts.

Thought Experiment

  • The speaker selects an individual from the audience (Jacqueline) and asks her to think.
  • By exploring someone else's thoughts, it challenges the notion that thinking is solely a first-person experience.

Sensing Thoughts

In this section, the speaker discusses sensing thoughts and how it relates to personal experiences.

Sensing Thoughts

  • The speaker explains that sensing thoughts encompasses all mental activities, including sensations.
  • It clarifies that when we claim to sense another person's emotions or thoughts, we are actually interpreting signs rather than directly experiencing them.

Understanding Mental Activity

This section emphasizes the broad definition of mental activity and its connection to personal experiences.

Mental Activity

  • The speaker highlights that mental activity includes sensations and is not limited to thinking.
  • It clarifies that interpreting signs in others does not equate to directly sensing their emotions or thoughts.

Interpreting Facial Expressions

Here, the speaker discusses interpreting facial expressions as a means of understanding others' emotions.

Facial Expressions

  • The speaker explains that when we claim to sense someone's anger or happiness, we are actually interpreting their facial expressions.
  • This interpretation is based on our own experiences of similar emotions.

Summary and Conclusion

In this final section, the speaker summarizes the main points discussed throughout the transcript.

Recapitulation

  • The speaker reiterates the importance of understanding mental activity beyond just thinking.
  • It emphasizes that interpreting signs in others is not equivalent to directly sensing their thoughts or emotions.

The Importance of "Je pense donc je suis"

This section discusses the significance of Descartes' famous phrase "Je pense donc je suis" (I think, therefore I am) and how it differs from other philosophical propositions.

Understanding the First-Person Perspective

  • Descartes' use of the first-person singular in "Je pense donc je suis" allows for a personal connection to the proposition.
  • This proposition unifies various characteristics found in previous formulations.

The Power of Self-Affirmation

  • The act of pronouncing and engaging with this proposition is an intellectual experience that modifies individuals who utter it.
  • Each pronunciation becomes a new act, leading to a unique understanding for each person.

Moving Beyond Historical Philosophy

  • Reading Descartes' works should not be seen as merely studying history but rather as engaging in a distinct and unparalleled thought process.
  • The cogito, particularly in the first and second meditations, offers everyone the opportunity to engage in authentic philosophical reflection.

Descartes' Philosophical Journey

This section explores Descartes' philosophical journey and his attempt to establish an absolute certainty through his cogito argument.

Time's Effect on Philosophy

  • Time has its impact on philosophers, as depicted by portraits of Descartes at different stages of his life.
  • The festive nature of time can lead to decay and destruction, symbolizing the challenges faced by philosophers.

The Battle Won by Cogito

  • Descartes achieved a triumph with his cogito argument at a young age when he formulated the meditations discussed earlier.
  • Portraits depict him developing his philosophy based on cogito, aiming to establish a solid foundation for his ideas.

Aging and Philosophical Skepticism

  • Even Descartes, as he aged, faced the weakening of his philosophical vigor and encountered skepticism.
  • The cogito argument's strength diminishes with each repetition, facing criticism and objections.

Critiques and Objections to Cogito

This section delves into various critiques and objections raised against Descartes' cogito argument.

Limitations of Cogito

  • Some argue that alternative propositions like "I walk, therefore I am" could yield similar results.
  • Critics claim that cogito restricts free reflection on the self rather than liberating it.

Questioning the Subject

  • Philosophers like Nietzsche suggest that the subject in cogito shifts from a grammatical function to a philosophical substance.
  • Jacques Lacan raises doubts about the identity between thinking and being in relation to self-consciousness.

Modern Perspectives on Certainty

  • Modern thinkers tend to be skeptical when philosophers discuss truth and certainty.
  • The pursuit of certainties is often seen as hiding hidden desires or an excessive quest for absolute truths.

Descartes' Enduring Legacy

This section acknowledges Descartes' contribution through his enduring proposition, despite its criticisms.

The Resilience of "Je pense donc je suis"

  • Descartes' legacy lies in his proposition's ability to resist, provoke thought, and stimulate reflection for almost four centuries.
  • Each time one utters "Je pense donc je suis," it holds true, but its meaning beyond that remains uncertain.

The Modern Perspective

  • Contemporary society tends to associate certainty more with exact sciences rather than philosophy or metaphysics.
  • Doubts arise when philosophers speak of truth and certainty, leading to suspicion and questioning their motives.

The Search for Truth

In this section, the speaker discusses the pursuit of truth and its significance during moments of doubt, worry, and fatigue. They emphasize the importance of intellectual perseverance and caution against the allure of skepticism.

The Value of Classical Philosophy

  • The search for truth is not entirely futile or senseless.
  • During times of doubt and exhaustion, it is essential to find comfort and confidence in classical philosophical concepts.
  • Descartes' first two meditations can provide reassurance and motivation to continue the intellectual journey.

Conclusion

The speaker concludes their remarks by expressing gratitude.

Gratitude

  • The speaker expresses gratitude to the audience.
  • They thank the listeners for their attention and encourage them to continue their work.

Video description

Comme l’écrivait Michel Foucault, les Méditations métaphysiques de Descartes ne sont pas seulement un texte démonstratif («un ensemble de propositions formant système») mais elles demandent aussi à leur lecteur d’accomplir une série d’exercices spirituels («être affecté par un ensemble de modifications formant exercice»). Cette intervention proposera donc d’effectuer les exercices proposés par les Première et Deuxième Méditationsde Descartes : du doute au fameux «cogito», ce sera l’occasion de tenter de vérifier, tout à la fois ensemble et chacun pour son propre compte, que la vérité existe, et qu’elle s’expérimente. Denis Moreau, ancien élève de l’École normale supérieure Ulm, agrégé et docteur en philosophie, professeur d’histoire de la philosophie moderne et de philosophie de la religion à l’université de Nantes, a notamment publié, outre l’édition, l’introduction et l’annotation d’ouvrages de Descartes: Activité physique et exercices spirituels. Essais de philosophie du sport (dir., avec P. Taranto, Vrin, 2008) ; Pour la vie? Court traité du mariage et des séparations (Seuil, 2014, rééd. en poche «Points sagesse», 2018) ; La Philosophie de Descartes (Vrin, 2016) ; Mort, où est ta victoire? (Bayard, 2017) ; Comment peut-on être catholique? (Seuil, 2018).

This intervention will therefore propose to carry out the exercises proposed by the First and Second Meditations of Descartes: from doubt to the famous "cogito", it will be an opportunity to try to verify, both together and individually, that the truth exists, and that it is experienced.
