动物和人类的有目的行为。
未来は誰にもわからない。だからこそ、今を大切に生きるべきだ。
——《在广州中国国民党恳亲大会的演说》(1923年10月15日)
The simple step of a courageous individual is not to take part in the lie. One word of truth outweighs the world. In keeping silent about evil, in burying it so deep within us that no sign of it appears on the surface, we are implanting it, and it will rise up a thousand fold in the future.
