Again I warn you, beware of philosophers and great reasoners. They will always be a snare to you, and will do you more harm than you will know how to do them good. They linger and pine away in discussing exterior trifles, and never reach the knowledge of the truth. Their curiosity is an insatiable spiritual avarice. They are like those conquerors who ravage the world without possessing it. Solomon, after a deep experience of it, testifies to the vanity of their researches.
—François Fénelon, Spiritual Progress
