He doubts the existence of objects because he has used his false opinions as foundations for everything else in life that he perceives to be true.
Descartes asserts that we can know our mind more readily than we can know our body. In support of this idea he gives the example of a piece of wax which is observed in its solid form and its liquid form.
After pointing out the difficulties of relying on the senses of the physical body to understand the nature of the wax he makes this claim: I contend that, based upon the arguments presented in the Second Meditation, Descartes shows that we can use our senses to help us understand the true nature of things, but the senses alone are inadequate to determine truth since they are often deceivedand that all that may be known with certainty truth are those things we know by our judgment, thinking, and understanding of them in our minds.
Descartes' argument does not necessarily reject any role of the senses in the process of understanding.
Steps of the Argument: Descartes began his argument in the First Meditation by questioning or calling into doubt everything that he knew.
After examining all the things he thought he knew about himself and the world he concluded the details of that argument are beyond the scope of this essay that the only thing he knew with absolute certainty is that I am, I exist Section Having established the fact that he has a real existence of some kind he then said But I do not yet understand sufficiently what I am--I who necessarily exist Section This line of questioning again the details of that argument are not necessary to this discussion led him to draw this conclusion: I am therefore precisely nothing but a thinking thing res cogitans 2 ; that is, a mind mensor intellect intellectusor understanding, or reason ratio -- words of whose meanings I was previously ignorant.
Yet I am a true thing and am truly existing; but what kind of thing? I have said it already: Note here that Descartes equates mind, intellect, understanding, reason, and soul with thinking 3. Having assured himself that he exists and that the essential nature of his self includes at least the capacity to think he then explored the question What else am I?
Section 27 and reached this conclusion: But then what am I? A thing that thinks res cogitans. A thing that doubts dubitansunderstands intelligensaffirms affirmansdenies neganswills volensrefuses nolensand that also imagines imaginans and senses sentiens Section Descartes acknowledges that thinking includes doubt, understanding, affirmation, denial, will volitionrefusal, imagination, and senses.
Descartes has said the senses sentiens are a part of the process of thinking cogitansnow he clarifies what he means when he speaks of the senses in the remainder of the text. Yet I certainly do seem to see, hear, and feel warmth.
This cannot be false. Properly speaking, this is what in me is called 'sensing sentire.
While it may appear that Descartes is attempting to redefine a term in common usage in a manner which would support his argument, it could also be argued that this clarification was intended only to point out that even if it were true that I do not in reality have a physical body as he assumed was possible in an earlier part of the argument which led to the conclusion: I think, therefore I exist this seeming to "see, hear, and feel warmth" would serve the same function in the process of cogitation as the actual physical senses would have if my body is real.
From these considerations I am beginning to know a little better what I am. But it still seems and I cannot resist believing that corporeal things--whose images are formed by thought, and which the senses themselves examine--are much more distinctly known than the mysterious 'I' which does not fall within the imagination Section Now the thought occurs to Descartes that perhaps I use my mind to understand abstract things like the nature of my existencebut it is with the senses that we explore and examine physical things.
Then he uses the example of a piece of wax to show that even physical things can only be clearly understood by inspecting them with the mind and not relying solely on the senses. I will not quote his entire development of the wax example, but summarize it thus: Observe a piece of wax.
It has a distinctive feel, odor, sound, taste, size, color, and temperature Section As the wax is heated each of those sensory attributes changes dramatically or is lost altogether Section Relying only on the physical senses would lead to the conclusion that the wax in its original form is a different substance than the wax in its later form, yet no one claims that both are not the same substance Section If the sensory elements of the wax are unreliable in helping us understand the wax, what are the essential non-sensory characteristics of wax?

In Meditation 1, one of the main premises that Descartes uses in his proof for the existence of God comes from the evil demon argument. The purpose of Descartes evil demon is to established doubt upon his belief that God is the sole figure who puts thoughts into his mind.
