Kant treats abstract humanity as sacred, not individuals [causal]
By freeing individuality from every restriction and special determination, and hence by making perpetually identical individuality—man in the abstract—the ultimate substance of personality, this era simultaneously elevated that abstraction to the ultimate value of personality. A man, says Kant, is certainly profane, but the mankind in him is sacred.
