“Other people's heads are too wretched a place for true happiness to have its seat.”

“Almost all of our sorrows spring out of our relations with other people. There is no more mistaken path to happiness than worldliness.”

“We will gradually become indifferent to what goes on in the minds of other people when we acquire a knowledge of the superficial nature of their thoughts, the narrowness of their views and of the number of their errors. Whoever attaches a lot of value to the opinions of others pays them too much honor.”

“What disturbs and depresses young people is the hunt for happiness on the firm assumption that it must be met with in life. From this arises constantly deluded hope and so also dissatisfaction. Deceptive images of a vague happiness hover before us in our dreams, and we search in vain for their original. Much would have been gained if, through timely advice and instruction, young people could have had eradicated from their minds the erroneous notion that the world has a great deal to offer them.”

“What a man is contributes much more to his happiness than what he has or how he is regarded by others.”

“The conviction that the world, and therefore man too, is something which really ought not to exist is in fact calculated to instil in us indulgence towards one another: for what can be expected of beings placed in such a situation as we are? From this point of view one might indeed consider that the appropriate form of address between man and man ought to be, not monsieur, sir, but fellow sufferer, compagnon de misères. However strange this may sound it corresponds to the nature of the case, makes us see other men in a true light and reminds us of what are the most necessary of all things: tolerance, patience, forbearance and charity, which each of us needs and which each of us therefore owes.”

“We forfeit three-fourths of ourselves in order to be like other people.”
