General knowledge quote

The general knowledge of mankind has been more effectively promoted by fear than by love; for fear tries to find out who the other is, what he knows, what he wants: it would be hazardous and detrimental to be deceived on this head. Love, on the other hand, has a secret craving to discover in the loved object as many beautiful qualities as possible, or to raise him as highly as possible: to be thus deceived would be delightful and propitious, – wherefore love indulges in it.

The dawn of day by Friedrich Nietzsche 

Quote about the fear of man

The fear of man brings a snare; it is a life of death, and the mind is so entirely suppressed by it, that it is capable of no relief; the animal spirits sink, and all the vigour of nature, which usually supports men under other afflictions, and is present to them in the greatest exigencies, fails them here.
