Democritus and Heraclitus were two philosophers, of whom…

““Democritus and Heraclitus were two philosophers, of whom the first, finding the condition of man vain and ridiculous, never went out in public but with a mocking and laughing face; whereas Heraclitus, having pity and compassion on this same condition of ours, wore a face perpetually sad, and eyes filled with tears. I prefer the first humor; not because it is pleasanter to laugh than to weep, but because it is more disdainful, and condemns us more than the other; and it seems to me that we can never be despised as much as we deserve. Pity and commiseration are mingled with some esteem for the thing we pity; the things we laugh at we consider worthless. I do not think there is as much unhappiness in us as vanity, nor as much malice as stupidity. We are not so full of evil as of inanity; we are not as wretched as we are worthless. Thus Diogenes, who pottered about by himself, rolling his tub and turning up his nose at the great Alexander, considering us as flies or bags of wind, was really a sharper and more stinging judge, to my taste, than Timon, who was surnamed the hater of men. For what we hate we take seriously. Timon wished us ill, passionately desired our ruin, shunned association with us as dangerous, as with wicked men depraved by nature. Diogenes esteemed us so little that contact with us could neither disturb him nor affect him, and avoided our company, not through fear of association with us, but through disdain of it; he considered us incapable of doing either good or evil… Our own peculiar condition is that we are as fit to be laughed at as able to laugh.””
