There are no secrets except the secrets that keep themselves.

There are no such things as secrets only truths that have yet to be revealed.

There are two kinds of secrets: secrets of nature and secrets about people. Natural secrets exist all around us; to find them, one must study some undiscovered aspect of the physical world. Secrets about people are different: they are things that people don’t know about themselves or things they hide because they don’t want others to know.

For example, a world without secrets would enjoy a perfect understanding of justice. Every injustice necessarily involves a moral truth that very few people recognize early on: in a democratic society, a wrongful practice persists only when most people don’t perceive it to be unjust. At first, only a small minority of abolitionists knew that slavery was evil; that view has rightly become conventional, but it was still a secret in the early 19th century. To say that there are no secrets left today would mean that we live in a society with no hidden injustices.

I have no secret thoughts... Or rather, they're not secret because I've withheld them — if they're unknown, it's because no one asked.

All the secrets of the world worth knowing are hiding in plain sight.

So when thinking about what kind of company to build, there are two distinct questions to ask: What secrets is nature not telling you? What secrets are people not telling you?

There are no secrets in science.

Men can know the nature of things

The man who can keep a secret may be wise, but he is not half as wise as the man with no secrets to keep.

Words were not given to man in order to conceal his thoughts.

We cannot count upon the secret being kept. It’s a fact of nature, and as somebody or other remarked long ago, Nature is a blabbermouth; ask the right question, and you’ll always get the answer.

There's no secret about success. Did you ever know a successful man who didn't tell you about it?

There is no such thing as magic, though there is such a thing as a knowledge of the secrets of nature.
