We can always get along better by reason and love of truth than by worry of conscience and remorse...we should strive to keep worry from our life.
Baruch SpinozaThe terms good and bad indicate no positive quality in things regarded in themselves, but are merely modes of thinking or notions, which we form from the comparison of things one with another. Thus one and the same thing can be at the same time good, bad, and indifferent. For instance, music is good for him that is melancholy, bad for him that mourns; for him that is deaf; it is neither good nor bad.
Baruch Spinoza
