“Curious how Love destroys every vestige of that politeness which the human race, in its years of evolution, has so painfully acquired.”

“Ever since history has been written, ever since philosophy has meditated, misery has been the garment of the human race.”

“Only now is the child finally divested of all that he has been.

“He who travels much has this advantage over others – that the things he remembers soon become remote, so that in a short time they acquire the vague and poetical quality which is only given to other things by time. He who has not traveled at all has this disadvantage – that all his memories are of things present somewhere, since the places with which all his memories are concerned are present.”
