To become reconciled to a friend with whom you have broken, is a form of weakness; and you pay the penalty of it when he takes the first opportunity of doing precisely the very thing which brought about the breach.
True brevity of expression consists in a man only saying what is worth saying, while avoiding all diffuse explanations of things which every one can think out for himself.
Faith is like love, it cannot be forced. Therefore it is a dangerous operation if an attempt be made to introduce or bind it by state regulations; for, as the attempt to force love begets hatred, so also to compel religious belief produces rank unbelief.
A man can be himself only so long as he is alone; and if he does not love solitude, he will not love freedom; for it is only when he is alone that he is really free.
Genius is its own reward; for the best that one is, one must necessarily be for oneself. . . . Further, genius consists in the working of the free intellect., and as a consequence the productions of genius serve no useful purpose. The work of genius may be music, philosophy, painting, or poetry; it is nothing for use or profit. To be useless and unprofitable is one of the characteristics of genius; it is their patent of nobility.
They tell us that suicide is the greatest piece of cowardice... 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.
Happiness belongs to those who are sufficient unto themselves. For all external sources of happiness and pleasure are, by their very nature, highly uncertain, precarious, ephemeral and subject to chance.
The auspices for philosophy are bad if, when proceeding ostensibly on the investigation of truth, we start saying farewell to all uprightness, honesty and sincerity, and are intent only on passing ourselves off for what we are not. We then assume, like those three sophists [Fichte, Schelling and Hegel], first a false pathos, then an affected and lofty earnestness, then an air of infinite superiority, in order to impose where we despair of ever being able to convince.
To free a man from error is to give, not to take away. Knowledge that a thing is false is a truth. Error always does harm; sooner or later it will bring mischief to the man who harbors it.
