One of the best things to come out of the home computer revolution could be the general and widespread understanding of how severely limited logic really is.

Digital world is changing its home, and I am in search of an evolution that exists beyond the digital world.

There is no parallel in the history of the world. This mighty subcontinent with all kinds of inhabitants has been brought under a plan which is titanic, unknown, unparalleled. And what is very important with regard to it is that we have achieved it peacefully and by means of an evolution of the greatest possible character.

We must wait for the official history of the Chinese Revolution to record in greater detail the invaluable work of our Japanese friends.

The evil of slavery and colonialism was that these oppressions kept their victims out of history, disconnected them from the evolutionary struggle.

Of all the things we have done, the most important - the one that history will record as the principal contribution of our generation - is that we understand how to turn the armed struggle into a Revolution; that we realized that it was essential to create a new mentality to build a new society.

Humanity has experienced many revolutionary changes over the course of history: revolutions in agriculture, in science, industrial production, as well as numerous political revolutions. But these have all been limited to the external aspects of our individual and collective lives.

Simon Bolivar, when history led him - and as Karl Marx said, men can make history, but only as far as history allows us to do so - when history took Bolivar and made him the leader of the independence process in Venezuela, he made that process revolutionary.

Revolutions are the locomotives of history.

I'm obsessed with insects, particularly insect flight. I think the evolution of insect flight is perhaps one of the most important events in the history of life. Without insects, there'd be no flowering plants. Without flowering plants, there would be no clever, fruit-eating primates giving TED Talks.

The revolutionary breakthrough will come with rockets that are fully and rapidly reusable. We will never conquer Mars unless we do that. It'll be too expensive. The American colonies would never have been pioneered if the ships that crossed the ocean hadn't been reusable.

You have to look at history as an evolution of society.

It is impossible to predict the time and progress of revolution. It is governed by its own more or less mysterious laws.

The ultimate purpose of religious life is to make this evolution move in a direction far more important to the destiny of the ego than the moral health of the social fabric which forms his present environment.

No innovation in the past 200 years has done more to save lives and improve health than the sanitation revolution triggered by invention of the toilet. But it did not go far enough. It only reached one-third of the world.

The revolutionary sees his task as liberation not only of the oppressed but also of the oppressor. Happiness can never truly exist in a state of tension.

I have a great respect for incremental improvement, and I've done that sort of thing in my life, but I've always been attracted to the more revolutionary changes. I don't know why. Because they're harder. They're much more stressful emotionally. And you usually go through a period where everybody tells you that you've completely failed.

Passion is needed for any great work, and for the revolution, passion and audacity are required in big doses.

The real power of the Buddha was that he had so much love. He saw people trapped in their notions of small separate self, feeling guilty or proud of that self, and he offered revolutionary teachings that resounded like a lion's roar, like a great rising tide, helping people to wake up and break free from the prison of ignorance.

The true revolutionary is guided by a great feeling of love. It is impossible to think of a genuine revolutionary lacking this quality.

What religion a man holds, to what race he belongs, these things are not important; the really important thing is this knowledge: the knowledge of God's plan for men. For God has a plan, and that plan is evolution.

My long struggles as a soldier of the Chinese Revolution have forced me to realize the necessity of facing hard facts. There will be neither peace, nor hope, nor future for any of us unless we honestly aim at political, social and economic justice for all peoples of the world, great and small.

It is my idea to make capitalism create socialism in China so that these two economic forces of human evolution will work side by side in future civilization.

Technology is the future, I have seen the third industrial revolution, and we are in the midst of the fourth industrial revolution.
