is a general prejudice we have, based on unreflectively held Platonic ideas and Cartesian divisions of reality, that ideas are somehow pure form, that they don’t need feelings, embodiments, dramatic performances and personalities to be real. But nothing could be farther from the truth. From the poetic crystal clarity of mathematics, to the dense, solemn vengefulness of communism and the fresh, sprinkling hope of environmentalism, all great ideas come with lived moods, visions and rituals.
