Karl Marx defines ugliness as a characteristic that may have a negative impact on a person’s lifestyle only when he is lacking in money. Here’s an excerpt from his essay, “The Power of Money,” (Economic and Philosophic Manuscripts of 1844):
“I am ugly, but I can buy for myself the most beautiful of women. Therefore I am not ugly, for the effect of ugliness–its deterrent power–is nullified by money. I, according to my individual characteristics, am lame, but money furnishes me with twenty-four feet. Therefore I am not lame. I am bad, dishonest, unscrupulous, stupid; but money is honored, and hence its possessor. Money is the supreme good, therefore its possessor is good. Money, besides, saves me the trouble of being dishonest: I am therefore presumed honest. I am brainless, but money is the real brain of all things and how then should its possessor be brainless? Besides, he can buy clever people for himself, and is he who has power over the clever not more clever than the clever? Do not I, who thanks to money am capable of all that the human heart longs for, possess all human capacities? Does not my money, therefore, transform all my incapacities into their contrary?”
I think Marx is wrong on this. It is not necessary that a man with money will buy beautiful women and clever people—he might end up squandering his money the ugly and the stupid. Money does not give you wisdom, and without wisdom you cannot identify real beauty and real cleverness.
