I have long been interested in the "essence" of things . . . and we've talked a great deal about this. I've mentioned before "The Veil of Appearance" (which I can never remember if it was Locke or Hume) which is a philosophical reasoning that as much knowledge as we can uncover about any said "thing," there's always something hidden. As is best and easily explained with humans. We, being sentient creatures with complexities far and beyond any "thing" in this world, have the ability to communicate with one another and understand one another through all sorts of methods. However, there is always at least one aspect no one will ever know . . . what it truly means to be you.

We might know this and that about a stone . . . but what really is a stone? Will we ever know what it truly means to be a stone?

And on another note . . . what is knowledge really? Is it already within us (prior [or at] birth) to have a certain quality of knowedge? Is all knowledge a direct and indirect result of the senses? How much knowledge is a posteriori and a priori? Is learning itself, knowledge?
