“When we teach ourselves and our children discipline, we are teaching them and ourselves how to suffer and also how to grow.”

M. Scott Peck (1936–2005) American psychiatrist

“The great force of history comes from the fact that we carry it within us, are unconsciously controlled by it in many ways, and history is literally present in all that we do.”

“Within the ranks of the people, democracy is correlative with centralism and freedom with discipline. They are the two opposites of a single entity, contradictory as well as united, and we should not one-sidedly emphasize one to the denial of the other. Within the ranks of the people, we cannot do without freedom, nor can we do without discipline; we cannot do without democracy, nor can we do without centralism. This unity of democracy and centralism, of freedom and discipline, constitutes our democratic centralism. Under this system, the people enjoy extensive democracy and freedom, but at the same time they have to keep within the bounds of socialist discipline.”

Mao Zedong (1893–1976) Chairman of the Central Committee of the Communist Party of China

On the Correct Handling of Contradictions Among the People
Original: (zh-CN) 民主自由都是相对的，不是绝对的，都是在历史上发生和发展的。在人民内部，民主是对集中而言，自由是对纪律而言。这些都是一个统一体的两个矛盾着的侧面，它们是矛盾的，又是统一的，我们不应当片面地强调某一个侧面而否定另一个侧面。在人民内部，不可以没有自由，也不可以没有纪律；不可以没有民主，也不可以没有集中。这种民主和集中的统一，自由和纪律的统一，就是我们的民主集中制。在这个制度下，人民享受着广泛的民主和自由；同时又必须用社会主义的纪律约束自己。这些道理，广大人民群众是懂得的。

“It becomes superfluous when people no longer need the external force of the tyrant to make them renounce their particular interests, but when they become "universal citizens" by directly identifying the core of their being with this universality - in short, people no longer need the external master when they are educated into doing the job of discipline and subordination themselves.”

Slavoj Žižek (1949) Slovene philosopher

“Denying oneself is an indulgence. The indulgence of denying is by far the worst; it forces us to believe that we are doing great things, when in effect we are only fixed within ourselves.”
