The human being cannot live in a condition of emptiness for very long: if he is not growing toward something, he does not merely stagnate; the pent-up potentialities turn into morbidity and despair, and eventually into destructive activities.
人类无法长期生活在空虚状态中：如果他不是朝着某个方向成长，他不仅会停滞不前，被压抑的潜能会变成病态和绝望，最终转化为破坏性行为。
The past is always with us, for it feeds the present.
圣人警戒于事情发展的苗头；愚人恐惧于事情明显暴露后。
预测未来的最好方法就是创造未来。
