Sharp, Not Solid

If man made himself the first object of study, he would see how
incapable he is of going further. How can a part know the whole? But he
may perhaps aspire to know at least the parts to which he bears some
proportion. But the parts of the world are all so related and linked to
one another, that I believe it impossible to know one without the other
and without the whole.
- Blaise Pascal, Pascal’s Pensées

This world, the eternally imperfect, an eternal contradiction's image and
imperfect image--an intoxicating joy to its imperfect creator:--thus did
the world once seem to me.
- Friedrich Nietzsche, “Thus Spake Zarathustra”

Therefore one ought to take a little heed not to call that force which is only a pretty knack of writing, and that solid which is only sharp, or that good which is only fine: "’Quae magis gustata, quam potata delectant’: everything that pleases, does not nourish’."
Montaigne, Essays, Chapter XIX. OF PHYSIOGNOMY.
