The word philosophy sounds high-minded, but it simply means the love of wisdom. If you love something, you don't just read about it you hug it, you mess with it, you play with it, you argue with it.

It seems to me that, in every culture, I come across a chapter headed 'Wisdom.' And then I know exactly what is going to follow: 'Vanity of vanities, all is vanity.'

Full of wisdom are the ordinations of fate.

If I am fool, it is, at least, a doubting one and I envy no one the certainty of his self-approved wisdom.

Who knows for what we live, and struggle, and die? Wise men write many books, in words too hard to understand. But this, the purpose of our lives, the end of all our struggle, is beyond all human wisdom.
