“There is no desire more natural than the desire of knowledge. (Il n'est desir plus naturel que le desir de connaissance)”

“Il n'est pas de chagrin qu'un livre ne puisse consoler.”

“There is nothing more unsociable than man, and nothing more sociable: unsociable by his vice, sociable by his nature.”

“La plus grande chose du monde, c'est de savoir être à soi.”

“READER, You have here an honest book; it does at the outset forewarn You that, in contriving the same, I have proposed to myself no other than a domestic and private end: I have had no consideration at all either to Your service or to my glory. My powers are not capable of any such design. I have dedicated it to the particular commodity of my kinsfolk and friends, so that, having lost me (which they must do shortly), they may therein recover some traits of my conditions and humours, and by that means preserve more whole, and more life-like, the knowledge they had of me. Had my intention been to seek the world's favour, I should surely have adorned myself with borrowed beauties: I desire therein to be viewed as I appear in mine own genuine, simple, and ordinary manner, without study and artifice: for it is myself I paint. My defects are therein to be read to the life, and any imperfections and my natural form, so far as public reverence hath permitted me. If I had lived among those nations, which (they say) yet dwell under the sweet liberty of nature's primitive laws, I assure thee I would most willingly have painted myself quite fully and quite naked. Thus, reader, myself am the matter of my book: there's no reason You should employ Your leisure about so frivolous and vain a subject. Therefore farewell.”

“El amor no es más que el deseo furioso de algo que huye de nosotros...”

“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.”
