Taoist philosophy is in many ways much more flexible than Confucianism. Taoist writers seek to avoid being "boxed" by rules, definitions and empty words. They encourage a sort of intuitive and non-logical way of seeking balance in the world by resisting the desire to interfere with normal processes of nature. Taoism emphasizes wu wei--enlightened non-action rather than needless bustle and "busy-work" for its own sake. Legalism emphasizes wu yu--active attempts to modify human behavior for the better by restraining the evil impulses of humanity in a rigid hierarchy of law. Confucianism, while not completely incompatible with either philosophy, suggests that thoughtful contemplation is necessary in making decisions rather than blindly following rules (the Legalist philosophy). Confucianism also rejects the irrationalism of Taoists.
