René Descartes

descartes quotes meditations

Because it's the mind that makes this determination. Now there is in me a passive faculty of sensory perception, that is a faculty for receiving and recognizing the ideas of sensible objects; but I could not make use of it unless there was also an active faculty, either in me or in something else, which produced or brought about these ideas. Similarly in the other cases. What is the cause of this cause of me? The idea of God captures the essential nature of God. We have to enquire how it is that the goodness of God does not prevent nature from deceiving us in this way.

Meditations on First Philosophy Summary

descartes quotes meditations

This investigation should be undertaken once at least in his life by anyone who has the slightest regard for truth, since in pursuing it the true instruments of knowledge and the whole method of inquiry come to light. Nevertheless, there is still the concept of a chiliagon, provided by the intellect: and from the concept we could deduce all kinds of geometrical truths, if we wanted to. English version by Webmaster using online resources. I can clearly and distinctly understand my mind apart from my body: my mind, but not my body, is essentially a thinking thing. But if we cannot entirely rely on our senses and the information we get from them, what can we do? He indeed held himself to be the sower and the reaper in one. It is grounded on the general truth, that the position of every point, the direction of every line, and consequently the shape and magnitude of every enclosed space, may be fixed by the length of perpendiculars thrown down upon two straight lines, or when the third dimension of space is taken into account upon three plane surfaces, meeting one another at right angles in the same point.

Quotes By René Descartes

descartes quotes meditations

This convinced me that I had nothing at all in my intellect that I had not previously had in sensation. If in full consciousness I could will to acquire a 'belief' irrespective of its truth, it is unclear that before the event I could seriously think of it as a belief, i. There is something sublime in the secrecy in which the really great deeds of the mathematician are done. I am, I exist — that is certain. My hope is that the answer to this will yield a new proof of the existence of a perfect being — a proof that it will be easier for me to keep in mind even when I relax my concentration. For had he seen a method of setting up a reasonable philosophy with the same unanswerable clarity as arithmetic, he would hardly have used any way other than this to establish a sect of followers, a thing which he so earnestly wanted.

Descartes Quotes

descartes quotes meditations

It seemed to me quite out of character for a body to be able to initiate movements, or to able to sense and think, and I was amazed that certain bodies — ·namely, human ones· — could do those things. I have said that error is essentially a privation — a lack of something that I should have — and now I know what this privation consists in. And would not the next step be to cast his eye over each apple in turn, and pick up and put back in the basket only those he saw to be sound, leaving the others? I cannot help believing them. Descartes endorses his early pre-reflective belief in the certainties of mathematics: The most certain truths of all were the kind which I recognized clearly in connection with shapes, or numbers or other items relating to arithmetic or geometry, or in general to pure and abstract mathematics. For I am convinced that his mechanics is full of errors, that his physics goes too fast, that his geometry is too narrow, and that his metaphysics is all these things. It does not prove that Descartes' dualism is false. Simply open your eyes and ignore what you cannot understand, and you will see that a labourer whose mind and knowledge extend no further than the edges of his furrow is no different essentially from the greatest genius, as would have been proved by dissecting the brains of Descartes and Newton; you will be convinced that the imbecile or the idiot are animals in human form, in the same way as the clever ape is a little man in another form; and that, since everything depends absolutely on differences in organisation, a well-constructed animal who has learnt astronomy can predict an eclipse, as he can predict recovery or death when his genius and good eyesight have benefited from some time at the school of Hippocrates and at patients' bedsides.

The argument offers a pragmatic reason, not a theoretical one. This conclusion is so obvious that I am confident that the human mind can know nothing more evident or more certain. Now it is obvious by the natural light that the total cause of something must contain at least as much reality as does the effect. Notice that in criticising the argument this way, we are not showing exactly what is wrong with Descartes' argument. Meditations On First Philosophy, Meditation 6, page 95 Thus what I thought I had seen with my eyes, I actually grasped solely with the faculty of judgment, which is in my mind. If I had derived my existence from myself, I would not now doubt or want or lack anything at all; for I would have given myself all the perfections of which I have any idea.

René Descartes's Quotes

descartes quotes meditations

If I had only been as wise as they say the savages persuaded themselves that the monkeys were, I never would have become known as a maker of books: Since it is said that they imagined that the monkeys could indeed speak, if they wanted to, but that they chose not to so lest they be forced to work. But viewed this way, the behaviour of all the bodies in the world, including our own sensory organs, can be explained in the one unified science. I now admit nothing that is not necessarily true: I am therefore, precisely speaking, only a thinking thing, that is, a mind, understanding, or reason, -- terms whose signification was before unknown to me. And when I take note of the fact that I doubt, or that I am a thing that is incomplete and dependent, there comes to mind a clear and distinct idea of a being that is independent and complete, that is, an idea of God. The clearest cases where you seem to be able to believe something because you want to are cases where the evidence does not compel you either way.

The first claim is plausible, in part. It looks just on the limit. I can clearly and distinctly understand the concept of a piece of wood. I guess he is actually a total genius. Belief, in general, does not seem to be under the control of the will. Veitch, A Discourse on Method 1912 , 53. We should resist believing anything that is not 'clear and distinct'.

Meditations on First Philosophy by Rene Descartes

descartes quotes meditations

The generalizations of mathematics, are, no doubt, a different thing from the generalizations of physical science; but in the difficulty of seizing them, and the mental tension they require, they are no contemptible preparation for the most arduous efforts of the scientific mind. What implications does this have for Descartes' argument? The more carefully I concentrate on these attributes, the less possible it seems that any of them could have originated from me alone. In the Fifth Meditation Descartes returns again to the topics of matter, and God. The first is that they would never be able to use speech, or other signs composed by themselves, as we do to express our thoughts to others. All the vivid sensations encountered by his naive self, sensations of their hardness and heat, of light, colours, smells, tastes and soundsthe blue of the sky, the rich smell of the earth, the tang of the sea 75 these sensed qualities resemble nothing in the world. First, though it is true that my knowledge is increasing, and that I have many potentialities that are not yet actual, this is all quite irrelevant to the idea of God, which contains absolutely nothing that is potential.
