You believe in first principles, and you are willing to build up knowledge on that foundation. That’s fine. Here you are talking strictly about “method”, rather than about certainty of knowledge; and perhaps Descartes method is not a practical way to go about things. I am not somebody that thinks that the principles underlying realism is a bad way to go about things; but it is not relevant to whether we can have “certain” knowledge of somethings objectivity beyond subjective appearance.You are making a typical Cartesian error in dealing with knowledge. The first step should never be criticism or a critiquing of knowledge. Rather the first step, should always be an attempt to explain the knowledge that we do have, what makes it possible.
For example; it appears to me that there are other people in what appears to be bodies. I am receiving information that suggests to me that because the bodies are behaving in a similar manner to my own and making consistent sounds like my own, it is reasonable of me to conclude that it is highly likely to be true that these bodies have minds like my own; in fact i take it for granted. However; i have no ability whatsoever of determining that this is in fact true to a degree of certainty that cannot fail. The same problem arises for the existence of the universe in general, since we cannot determine that appearances aplly to objectively real objects. It seems to me that what Descartes was trying to do is create a superior metaphysics free of speculative probability or failure. I think that metaphysics can get us to God regardless of whether the particular appearances we experience are objectively true or not. I think Descartes got us some of the way by cogito ergo sum. I think that i have demonstrated to my self that we can have certain knowledge of God on the foundation of “i think there for i am” (i use a different to Descartes). What we cannot have certain knowledge of, however, is the physical universe in its “particularity”. We cannot have any certain knowledge of particularities.
We might have no practical reason to doubt, but we still don’t have any “certain knowledge” that appearances correspond to objective reality. We distinguish illusion not by knowing what is real, but by first assuming that our consistent experience is objectively real. We take it for granted because we experience it all the time from the day of our birth; and then when we find irrational “inconsistencies” in that information we become speculative of what we are receiving.We can only speak of illusion and such because we know what real is. Otherwise, there is no basis for asserting or distinguishing something is illusory.
For example two people are in a desert dehydrating. One of them sees an oasis appear out of nowhere in front of his eyes. His companion, however, doesn’t see it and says, “you are not really seeing an oasis”. But because it seems so objectively real, the guy jumps into the oasis expecting to experience the delights of H20, but instead gets a mouth full of sand. Why did he do it? It was because, for him, the illusion was very real.
If you have ever seen the “matrix”, you will see that this film presents to us the possibility of ones experience being a life long illusion and people never knowing it.
That some idea leads to a negative result is not by itself necessarily proof that the founder of such an idea is wrong. That somebody likes cheese and pickle sandwiches is not a proof that i will like cheese and pickle sandwiches.Descartes knew his position would lead to solipsism, which is why he had to resort to God as guaranteeing our ideas.
It entails it or suggests it, but as i said, i don’t believe that it truly or necessarily undermines knowledge of “all” objective reality. It merely undermines those realities that are the objects of empirical science. It seems to me that Gods existence can be proven from the foundation of cogito ergo sum just as effectively as from a position realism. Of course, i am only speaking here in respect of absolute “certainty”. I am not saying that we have to begin with cogito ergo sum. In respect of the science, i believe that the sciences are valid in so far as “empirical knowledge” (which is a probabilistic knowledge) is concerned .David Hume realized that Descartes position necessarily entailed skepticism
