Innovation is impossible for people who need guarantees.

Not inventing, and not adopting new ideas, can itself be both dangerous and immoral.

I disbelieve in specialization and... experts. ...[P]aying too much respect to the specialist ...[is] destroying the commonwealth of learning, the rationalist tradition, and science ...

Anyone who says failure is not an option has also ruled out innovation.

Anything new, anything worth doing, can't be recognized.

The chief enemy of creativity is good sense.

You can’t experiment with tradition.

You can’t have a new idea ’til you’ve got rid of an old one.

Acting only when you know the outcome means you can only do what's already been done.

Innovation is impossible for people who need guarantees.

Whoever innovates something in this matter of ours that is not part of it, will have it rejected.

The problem with experts is that they do not know what they do not know.

Intellectual brilliance is no guarantee against being dead wrong.

Any “knowledge” incapable of being revised with advances in data and human thinking does not deserve the name of knowledge.

You can’t destroy knowledge. You can stamp it under and burn it up and forbid it to be, but somewhere it will survive.
