The philosophical question before us is, when we make an observation of our track in the past, does the result of our observation become real in the same sense that the final state would be defined if an outside observer were to make the observation?

Richard P. Feynman

Moral truth, resting entirely upon the ascertained consequences of actions, supposes a process of observation and reasoning.

Frances Wright

Intuition is for thinking what observation is for perception. Intuition and observation are the sources of our knowledge.

Rudolf Steiner

There are three principal means of acquiring knowledge... observation of nature, reflection, and experimentation. Observation collects facts; reflection combines them; experimentation verifies the result of that combination.

Denis Diderot

From the dawn of exact knowledge to the present day, observation, experiment, and speculation have gone hand in hand; and, whenever science has halted or strayed from the right path, it has been, either because its votaries have been content with mere unverified or unverifiable speculation (and this is the commonest case, because observation and experiment are hard work, while speculation is amusing); or it has been, because the accumulation of details of observation has for a time excluded speculation.

Thomas Huxley

Observe, and in that observation there is neither the "observer" nor the "observed" - there is only observation taking place.

Jiddu Krishnamurti

The two fulcra of medicine are reason and observation. Observation is the clue to guide the physician in his thinking.

Giorgio Baglivi

Let observation with extended observation observe extensively.

Alfred Lord Tennyson

Self-observation brings man to the realization of the necessity of self-change. And in observing himself a man notices that self-observation itself brings about certain changes in his inner processes. He begins to understand that self-observation is an instrument of self-change, a means of awakening.

G. I. Gurdjieff

It is a commonplace executive observation that businesses exist to make money, and the observation is usually allowed to go unchallenged. It is, however, a very limited statement about the purposes of business

Daniel Katz

A man's knowledge may be said to be mature, in other words, when it has reached the most complete state of perfection to which he, as an individual, is capable of bringing it, when an exact correspondence is established between the whole of his abstract ideas and the things he has actually perceived for himself. His will mean that each of his abstract ideas rests, directly or indirectly, upon a basis of observation, which alone endows it with any real value; and also that he is able to place every observation he makes under the right abstract idea which belongs to it.

Arthur Schopenhauer

There is an overwhelming mass of authentic evidence which can be cited as: direct observation, indirect observation, and supporting evidence or indication.

Morris K. Jessup

In matters of observation chance favors only the prepared mind. (not literal translation) - Dan's les champs de observation le hasard ne favorise que les esprits prepares.

Louis Pasteur

In my experience and observation, senior appointments are rarely based entirely on merit.

Martha Nussbaum

We have three approaches at our disposal: the observation of nature, reflection, and experimentation. Observation serves to assemble the data, reflection to synthesise them and experimentation to test the results of the synthesis. The observation of nature must be assiduous, just as reflection must be profound, and experimentation accurate. These three approaches are rarely found together, which explains why creative geniuses are so rare.

John Dewey

The true method of discovery is like the flight of an aeroplane. It starts from the ground of particular observation; it makes a flight in the thin air of imaginative generalization; and it again lands for renewed observation rendered acute by rational interpretation.

Alfred North Whitehead
