Some cause must unite the separate temporal sections of a person [Descartes]
|
|
Full Idea:
Because the entire span of one's life can be divided into countless parts, each one wholly independent of the rest, it does not follow from the fact that I existed a short time ago that I exist now, unless some cause creates and preserves me each moment.

From:
René Descartes (Meditations [1641], §3.49)
|
|
A reaction:
How could I 'prove' that this computer is the same computer as it was five minutes ago, even after I have accepted the straightforward existence of the computer? This is the Enlightenment Project, the mad desire to prove absolutely everything.

Since I only observe myself to be thinking, I conclude that that is my essence [Descartes]
|
|
Full Idea:
Since I do not observe that any other thing belongs necessarily to my nature or essence except that I am a thinking thing, I rightly conclude that my essence consists in this alone, that I am a thinking thing, or substance whose essence is thinking.

From:
René Descartes (Meditations [1641], §6.78)
|
|
A reaction:
This actually appears to be my favourite confusion - of episemology with ontology. Compare 'whenever I see him he is smiling, so he must be happy'. Personally I am happy to say that my essence is thinking, as long as it needn't be conscious.

For Descartes a person's essence is the mind because objects are perceived by mind, not senses [Descartes, by Feuerbach]
|
|
Full Idea:
For Descartes the essence of corporeal things is not an object of the senses, but only of the mind; and hence it is not the senses but the mind that is the essence of the perceiving subject, that is, of man.

|
From:
report of René Descartes (Meditations [1641], 2) by Ludwig Feuerbach - Principles of Philosophy of the Future §17
|
|
A reaction:
This, of course, is why Descartes' approach can lead to idealism and solipsism, whereas the other approach leads to empiricism and animalism (Idea 6669).
