Who said “Beauty as we feel it is something indescribable; what it is or what it means can never…”?

“Beauty is the purgation of superfluities.”

“Beauty itself is but the sensible image of the infinite.”

“The flowers anew, returning seasons bring! But beauty faded has no second spring.”

“The beautiful seems right by force of beauty, and the feeble wrong because of weakness.”

“Beauty is truth, truth beauty -- that is all ye know on earth, and all ye need to know.”

“Skepticism is the chastity of the intellect.”

“Our dignity is not in what we do, but in what we understand.”

“Perhaps the only true dignity of man is his capacity to despise himself.”

“The young man who has not wept is a savage, and the old man who will not laugh is a fool.”

“The empiricist... thinks he believes only what he sees, but he is much better at believing than at seeing.”

“Let a man once overcome his selfish terror at his own finitude, and his finitude is, in one sense, overcome.”
