You will never get to the irreducible definition of anything because you will never be able to explain why you want to explain, and so on. The system will gobble itself up.
I love wisdom. And you can never be great at anything unless you love it. Not be in love with it, but love the thing, admire the thing. And it seems that if you love the thing, and you don't just want to possess it, it will find you.
For if you know what you want, and will be content with it, you can be trusted. But if you do not know, your desires are limitless and no one can tell how to deal with you. Nothing satisfies an individual incapable of enjoyment.
