Humans must first of all eat to live. Taste is secondary. Mozi (468?-376 BC) opposed extravagance in favor of frugality and utility. He argued that an extravagant way of life was wasteful of labor and raw materials. He prioritized eating one’s fill and dressing warmly over aesthetic demands. It was not that he abhorred beauty or was unable to appreciate it. Rather, he adopted functionality and usefulness as his criteria for judging beauty, and believed that whatever was impractical or of only formal elegance had no true beauty. Whereas Confucian philosophers valued both form and content, arguing that external features and inner substance were equally important, Mozi placed substance well above form, which also illustrates the relationship between aesthetics and practicality.
