The true method of knowledge is experiment.

Experience presents itself as the method, and the only method, for getting at nature, penetrating its secrets, and wherein nature empirically discloses (by the use of empirical method in natural science) deepens, enriches and directs the further development of experience.

An experiment is a question which we ask of Nature, who is always ready to give a correct answer, provided we ask properly, that is, provided we arrange a proper experiment.

The basis of science is the empirical method, which uses the senses to build up a picture of the world; but science tells us that our senses have evolved to help us get by, not to show us the world as it is. Science is only a systematic examination of our impressions, and in the end all each of us has left are our own sensations ... The end-result of the empirical method, then, is that each individual is left alone with their own experiences. We can escape this solitude, Balfour suggested, only if we accept that there is a divine mind.

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

Experimentation is the essence of living a satisfying, productive, fulfilling life. The more you Experiment, the more you learn, and the more you’ll achieve.

This grasping of the whole is obviously the aim of science as well, but it is a goal that necessarily lies very far off because science, whenever possible, proceeds experimentally and in all cases statistically. Experiment, however, consists in asking a definite question which excludes as far as possible anything disturbing and irrelevant. It makes conditions, imposes them on Nature, and in this way forces her to give an answer to a question devised by man. She is prevented from answering out of the fullness of her possibilities since these possibilities are restricted as far as practible. For this purpose there is created in the laboratory a situation which is artificially restricted to the question which compels Nature to give an unequivocal answer. The workings of Nature in her unrestricted wholeness are completely excluded. If we want to know what these workings are, we need a method of inquiry which imposes the fewest possible conditions, or if possible no conditions at all, and then leave Nature to answer out of her fullness.

The scientific method is the only authentic means at our command for getting at the significance of our everyday experiences of the world in which we live...scientific method provides a working pattern of the way in which and conditions under which experiences are used to lead ever onward and outward.

The method of scientific investigation is nothing but the expression of the necessary mode of working of the human mind.

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

And because this Experimental Science is wholly ignored by the general run of students, for that reason I can not convince people of its utility unless I show at the same time its excellence and its property. This science alone, then, knows how to test perfectly by experience what can be done by nature, what by the industry of art, what by imposture; what the incantations, conjurations, invocations, deprecations, sacrifices (which are magical devices) seek and dream of; and what is done in them, so that all falsity may be removed and that only the truth of art and nature be retained. This science alone teaches one to consider all the insanities of magicians, not that they may be confirmed but that they may be avoided, just as logic considers sophistical argument.

The experimental universal is acquired by us, whose mind's eye is not purely spiritual, only through the help of the senses. For when the senses several times observe two singular occurrences, of which one is the cause of the other or is related to it in some other way, and they do not see the connection between them... And from this perception repeated again and again and stored in memory, and from the sensory knowledge from which the perception is built up, the functioning of the reasoning begins. The functioning reason therefore begins to wonder and to consider whether things really are as the sensible recollection says, and these two lead the reason to experiment... But when he has administered many times with the sure exclusion of all other things [that could be mistaken for the cause]... then there is formed in the reason this universal... and this is the way in which it comes from sensation to a universal experimental principle.

Experimental Science is represented by Bacon, in the sixth part of the Opus Maius, as a general method for the purpose of checking the results reached by mathematical processes, and also of prompting further researches in fresh fields of inquiry. He saw its bearing and its importance as a universal method of research.

The word experiment derives from 'experimentum' - that which has been experienced and what , for the writer , has been experienced is the work of his great predecessors
