Seneca · On quibbling as unworthy of the philosopher

Letters 48.9

Tell them what nature has made necessary, and what superfluous; tell them how simple are the laws that she has laid down, how pleasant and unimpeded life is for those who follow these laws, but how bitter and perplexed it is for those who have put their trust in opinion rather than in nature.

I should deem your games of logic to be of some avail in relieving men’s burdens, if you could first show me what part of these burdens they will relieve. What among these games of yours banishes lust? Or controls it? Would that I could say that they were merely of no profit! They are positively harmful. I can make it perfectly clear to you whenever you wish, that a noble spirit when involved in such subtleties is impaired and weakened.
