Who said “There is a level of cowardice lower than that of the conformist: the fashionable…”?

“Cowards die many times before their deaths; The valiant never taste of death but once.”

“That man is not truly brave who is afraid either to seem or to be, when it suits him, a coward.”

“My valor is certainly going, it is sneaking off! I feel it oozing out as it were, at the palms of my hands!”

“How many feasible projects have miscarried through despondency, and been strangled in their birth by a cowardly imagination.”

“Cowardice, as distinguished from panic, is almost always simply a lack of ability to suspend the functioning of the imagination.”

“Wealth is the product of man's capacity to think.”

“A building has integrity just like a man. And just as seldom.”

“Upper classes are a nation's past, the middle class its future.”

“I don't build in order to have clients. I have clients in order to build.”

“To achieve, you need thought. You have to know what you are doing and that's real power.”

“The purpose of morality is to teach you, not to suffer and die, but to enjoy yourself and live.”
