For where did Dante get the material for his Hell, if not from this actual world of ours? - Arthur Schopenhauer

"NOT to my contemporaries, not to my compatriots but to
mankind I commit my now completed work in the confidence that it will not be without value for them, even
if this should be late recognised, as is commonly the lot
of what is good. For it cannot have been for the passing
generation, engrossed with the delusion of the moment,
that my mind, almost against my will, has uninterruptedly
stuck to its work through the course of a long life.

preface to the second edition of "the world as will and representation

They tell us that suicide is the greatest piece of cowardice; that only a madman could be guilty of it; and other insipidities of the same kind; or else they make the nonsensical remark that suicide is wrong; when it is quite obvious that there is nothing in the world to which every man has a more unassailable title than to his own life and person.

Ordinary people merely think how they shall 'spend' their time; a man of talent tries to 'use' it.
