Essays and Aphorisms (again) by Arthur Schopenhauer

“As a reliable compass for orientating yourself in life nothing is more useful than to accustom yourself to regarding this world as a place of atonement, a sort of penal colony. When you have done this you will order your expectations of life according to the nature of things and no longer regard the calamities, sufferings, torments and miseries of life as something irregular and not to be expected but will find them entirely in order, well knowing that each of us is here being punished for his existence and each in his own particular way. This outlook will enable us to view the so-called imperfections of the majority of men, i.e. their moral and intellectual shortcomings and the facial appearance resulting therefrom, without surprise and certainly without indignation: for we shall always bear in mind where we are and consequently regard every man first and foremost as a being who exists only as a consequence of his culpability and whose life is an expiation of the crime of being born.
“The conviction that the world, and therefore man too, is something which really ought not to exist is in fact calculated to instill 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 miseres. 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.”
