“Change is the end result of all true learning.”

“Emotions are the sums created by details, whether those details are true or not.”

“Round and round he walked, and so learned a very valuable thing: that no emotion is the final one.”

“In the end, the sum of my vices is all me.”

“In the end things must be as they are and have always been--the great things remain for the great, the abysses for the profound, the delicacies and thrills for the refined, and, to sum up shortly, everything rare for the rare.”

“We must learn to look at problems all-sidedly, seeing the reverse as well as the obverse side of things. In given conditions, a bad thing can lead to good results and a good thing to bad results.”

“Learn to use your emotions to think, not think with your emotions.”

“The sum of things to be known is inexhaustible, and however long we read, we shall never come to the end of our story-book."

(, 3 October 1892)”

“The end justifies the means. Sometimes you have to do the wrong thing to get the right result.”
