Asceticism is the right way of thinking for those who have to extirpate their sensual drives because they are ravening beasts of prey. But only for those!

When we think of all the things we want to do with our other half the answer should be simple; we should want to do absolutely everything with them. We should want to experience everything, feel everything, see everything with no one but them by our sides. When we look back on our lives it's not the things we did do with them that we'll regret, it's the things we didn't do.
So far there has been no philosopher in whose hands philosophy has not grown into an apology for knowledge; on this point, at least, every one is an optimist, that the greatest usefulness must be ascribed to knowledge. They are all tyrannized over by logic, and this is optimism in its essence.
When one speaks of humanity, the idea is fundamental that this is something which separates and distinguishes man from nature. In reality, however, there is no such separation: "natural" qualities and those called truly "human" are inseparably grown together. Man, in his highest and noblest capacities, is wholly nature and embodies its uncanny dual character. Those of his abilities which are terrifying and considered inhuman may even be the fertile soil out of which alone all humanity can grow in impulse, deed, and work.
