Descartes asserts that we can know our mind more readily than we can know our body.
While distinguishing rigorous knowledge scientia and lesser grades of conviction persuasioDescartes writes: I distinguish the two as follows: But since I see that you are still stuck fast in the doubts which I put forward in the First Meditation, and which I thought I had very carefully removed in the succeeding Meditations, I shall now expound for a second time the basis on which it seems to me that all human certainty can be founded.
First of all, as soon as we think that we correctly perceive something, we are spontaneously convinced that it is true. Now if this conviction is so firm that it is impossible for us ever to have any reason for doubting what we are convinced of, then there are no further questions for us to ask: Replies 2, AT 7: As my certainty increases, my doubt decreases; conversely, as my doubt increases, my certainty decreases.
The requirement that knowledge is to be based in complete, or perfect certainty, amounts to requiring a complete absence of doubt — an indubitability, or inability to undermine one's conviction.
Descartes' methodic emphasis on doubt, rather than on certainty, marks an epistemological innovation.
It has also a distinctively epistemic character, involving a kind of rational insight. The above texts block quoted are among Descartes' clearest statements concerning the brand of knowledge he seeks.
Yet they raise questions about the extent to which his account is continuous with other analyses of knowledge. Prima facie, his characterizations imply a justified belief analysis of knowledge — or in language closer to his own and where justification is construed in terms of unshakabilityan unshakable conviction analysis.
There's no stated requirement that the would-be knower's conviction is to be true, as opposed to being unshakably certain. Is truth, therefore, not a requirement of Descartes' brand of strict knowledge? Many will balk at the suggestion. It might therefore seem clear, whatever else is the case, that Descartes conceives of knowledge as advancing truth.
Without denying this, let me play devil's advocate. It is not inconsistent to hold that we're pursuing the truth, even succeeding in establishing the truth, and yet to construe the conditions of success wholly in terms of the certainty of our conviction — i.
Thus construed, to establish a proposition just is to perceive it with certainty; the result of having established it — i.
Truth is a consequence of knowledge, rather than its precondition. What is it to us that someone may make out that the perception whose truth we are so firmly convinced of may appear false to God or an angel, so that it is, absolutely speaking, false?The Rene Descartes: Meditations on First Philosophy Community Note includes chapter-by-chapter summary and analysis, character list, theme list, historical context, author biography and quizzes written by community members like you.
His greatness is found in his contribution to the thinking process itself in the form of analysis and synthesis, as Spinoza suggests, (Spinoza, p. 3) and his methodological or deductive process of discovering knowledge.
