All life is an experiment. The more experiments you make the better.

Live your life as an experiment.

You do an experiment because your own philosophy makes you want to know the result. It’s too hard, and life is too short, to spend your time doing something because someone else has said it’s important. You must feel the thing yourself…

To be intelligently experimental is but to be conscious of [the] intersection of natural conditions so as to profit by it instead of being at its mercy. The Christian idea of this world and this life as a probation is a kind of distorted recognition of the situation; distorted because it applied wholesale to one stretch of existence in contrast with another, regarded as original and final

Just as scientific experimentation is informed by theory, startup experimentation is guided by the startup’s vision. The goal of every startup experiment is to discover how to build a sustainable business around that vision.

An experiment is a question which science poses to Nature and a measurement is the recording of Nature's answer.

From now on, everything you do in this book, and after, should be viewed as an experiment. This has been a profound shift for people who worry that “starting a business” is this big daunting thing. Experiments are supposed to fail. And should they fail, you just take what you’ve learned and try again a little bit differently.

Don't be too timid and squeamish about your actions. All life is an experiment. The more experiments you make the better.

mistakes are just opportunities for learning something new — which, after all, is what scientific experiments are all about.

Should philosophy guide experiments, or should experiments guide philosophy?

Do not be too timid and squeamish about your actions. All life is an experiment. The more experiments you make the better. What if they are a little coarse, and you may get your coat soiled or torn? What if you do fail, and get fairly rolled in the dirt once or twice? Up again; you shall never be so afraid of a tumble. — Ralph Waldo Emerson

Art is sort of an experimental station in which one tries out living

Experiment is the only means of knowledge at our disposal. Everything else is poetry, imagination.

Part Three, that part of formal scientific method called experimentation, is sometimes thought of by romantics as all of science itself because that’s the only part with much visual surface. They see lots of test tubes and bizarre equipment and people running around making discoveries. They do not see the experiment as part of a larger intellectual process and so they often confuse experiments with demonstrations, which look the same. A man conducting a gee-whiz science show with fifty thousand dollars’ worth of Frankenstein equipment is not doing anything scientific if he knows beforehand what the results of his efforts are going to be. A motorcycle mechanic, on the other hand, who honks the horn to see if the battery works is informally conducting a true scientific experiment. He is testing a hypothesis by putting the question to nature. The TV scientist who mutters sadly, “The experiment is a failure; we have failed to achieve what we had hoped for,” is suffering mainly from a bad scriptwriter. An experiment is never a failure solely because it fails to achieve predicted results. An experiment is a failure only when it also fails adequately to test the hypothesis in question, when the data it produces don’t prove anything one way or another.
