Exploring descartes overall objective about knowledge in meditations

Why Meditationes de prima philosophia? And why in Latin? The 3 main goals of the Meditations: Demonstrate the existence of God and the immortality of the soul. The structure of the Meditations: How one should put oneself in the shoes of the narrator.

Solid foundation needed in the sciences and the search for an Archimedean unshakable point. The doubt and its role: The levels of doubt: God might induce me to make mistakes Objection: Perhaps there's no God Reply: Then my capacity to err is still present because my origin would be imperfect. The evil demon, who takes over the deceiver role that only blasphemy could attribute to God. The insulation of doubt, i.

Second Meditation In the second Meditation, Descartes starts to emerge from the doubt by admitting only what he knows to be true and progressing from it by indubitable principles. The cogito 'I am, I exist' is true whenever I think.

Descartes overall objective in the meditations is to question knowledge

I think, therefore I am; I know I exist for as long as I think. If I stop thinking I might go out of existence. Why 'I walk, therefore I am' won't do. Starting point of cogito cannot be 'I think', but 'there are thoughts'. But from this one cannot get the 'I' of 'I exist'. A thinking thing, i. I seem to hear, see, etc.

Five claims ultimately included in "I am a thinking thing": I think Thought is essential to me.

Thought is the only property essential to me I am essentially a thinking thing and essentially non-material. In Meditation II, Descartes accepts 1-3, leaving the remaining two for later.

B The wax One must resist the temptation to read too much metaphysics in this passage, because its nature is epistemological. In it, Descartes attempts to reach 3 epistemological conclusions: Descartes makes a good case for 1; 2. However, he fails to prove 3: Third Meditation The Meditation has two goals: The Meditation starts by: I know I'm a thinking thing, and I know I'm right because I perceive the cogito clearly and distinctly.

René Descartes: Scientific Method

Hence, I conclude that clearness and distinctness are marks of truth. Descartes doesn't tell us what the criteria for clearness and distinctness are; however, the cogito seems to satisfy two: Descartes provides a double classification of ideas: Modes of thought with the exception of judgments can never be 'false': Judgments, by contrast, can be false.

For example, willing needs an intentional object, and hence a representation of that object. Natural light as in the cogito vs. How nature, through sensation, pushes me to believe in things which can be doubted, e.

  • What then, is this "I" that doubts, that may be deceived, that thinks?
  • The Meditation, which had started by trying to efface sensible images, concludes with the the contemplation of God.

But this can be easily doubted because: Continuation of the critique of the senses Critique of the Scholastic theory of sensation with its intentional species. The proofs for God's existence Some preliminaries: For example, if A is an idea of a hard stone X, then hardness is objectively in A, subjectively and formally in X, and eminently in God because God can create hardness.

How this somewhat reasonable a property cannot come from nothing The ultimate cause of an idea I containing F objectively representing F must contain F formally or eminently causal principle of representation. How this seems less reasonable. First proof for God's existence. I find within my mind the idea of God, i. But divine infinity cannot be understood as mere lack of finitude, and consequently its idea is not merely that of an indefinite or potential infinity The idea of God not materially false e.

Hence, the causal principle of representation entails that the idea of God is caused by God himself. Descartes rejects the empiricist view of infinity as mere lack of completion Descartes claims that although we can understand infinity, we cannot comprehend it. Second proof of God's existence: Since the senses obfuscate this result, Descartes inquires whether he could exists if God didn't. He so provides a second argument in the form "If I exist, then God exists," which has the first argument as a part.

I exist; hence, either 1 I have no cause; or 2 I have a cause. But 1 is false a cause for everythinghence 2 is true. If I have a cause, then, either a I caused myself, or b a being or beings different from me and from God caused me, or c God caused me. But a and b are false; so, God caused me, and hence he exists.

I am not self-caused because: I would have made myself omniscient, which I could have easily done since it is harder to cause a substance myself than a property of it my knowledge.

Descartes here uses the Aristotelian idea that a substance is more fundamental than its properties. A cause must be contemporaneous with its effect.

Hence, my existence in the past cannot be the cause of my existence in the present. So, all parts of my life span are causally independent of each other. But I'm not aware of any power whereby I produce myself now. But if I had such power, since I'm a thinking thing, I'd be aware of it.

Moreover, my parents do not cause my existence because they don't conserve me Problems: Is he justified in looking at himself just qua a thinking thing? Transparency of the mind taken as self-evident. To be looked at later. The idea of God is not adventitious, since it did not come to me unexpectedly, like ideas of sensible things do, and not factitious, since I'm unable to change anything in it. Hence, it is innate, i.

So, God exists and being perfect cannot be deceitful. This guarantees that what I perceive clearly and distinctly through natural light is true even when I don't consider the proof any longer.

The Meditation, which had started by trying to efface sensible images, concludes with the the contemplation of God. Hence, the Meditation starts with images and ends with concepts 7.
