In all of my hating on Descartes, I found a quote that made me think, which surprised me." For it is obvious that whatever is true is something, and I have already demonstrated at some length that all I know clearly is true." At first I thought I would be able to go off on a field day tearing Descartes apart about how stupid and obvious this statement is and how this statement is obviously true when referring to Descartes because his conclusions and epiphanies are so simple and primative so they would be impossible to be false. But it is actually a well thought out analysis of what one clearly knows. Think about it, if you have the thought that a certain person is a nice truthful human being, and on every encounter this is the vibe that they gave off to you, but you don't know the person in actuality is a backstabbing liar, you obviously don't know the person is nice, you think the person is nice. But, there is a "know" about this fact. You know it is true that you think the person is nice. And this rule can be applied to any thought really. That is why that statement caught my eye. It's not the world's greatest discovery, but I got something out of it.
