"For the truth of the conclusions of physical science, observation is the supreme Court of Appeal. It does not follow that every item which we confidently accept as physical knowledge has actually been certified by the Court; our confidence is that it would be certified by the Court if it were submitted. But it does follow that every item of physical knowledge is of a form which might be submitted to the Court. It must be such that we can specify (although it may be impracticable to carry out) an observational procedure which would decide whether it is true or not. Clearly a statement cannot be tested by observation unless it is an assertion about the results of observation. Every item of physical knowledge must therefore be an assertion of what has been or would be the result of carrying out a specified observational procedure." »Sir Arthur Eddington, The Philosophy of Physical Science

"There is no observation more frequently made by such as employ themselves in surveying the conduct of mankind, than that marriage, though the dictate of nature, and the institution of Providence, is yet very often the cause of misery, and that those who enter into that state can seldom forbear to express their repentance, and their envy of those whom either chance or caution hath withheld from it." »Samuel Johnson

"Do not believe in anything simply because you have heard it. Do not believe in anything simply because it is spoken and rumored by many. Do not believe in anything simply because it is found written in your religious books. Do not believe in anything merely on the authority of your teachers and elders. Do not believe in traditions because they have been handed down for many generations. But after observation and analysis, when you find that anything agrees with reason and is conducive to the good and benefit of one and all, then accept it and live up to it." »The Buddha

"He who lets the world, or his own portion of it, choose his plan of life for him, has no need of any other faculty than the ape-like one of imitation. He who chooses his plan for himself, employs all his faculties. He must use observation to see, reasoning and judgment to foresee, activity to gather materials for decision, discrimination to decide, and when he has decided, firmness and self-control to hold to his deliberate decision." »John Stuart Mill, On Liberty, 1859

"Women never reason and therefore they are, comparatively, seldom wrong. They judge instinctively of what falls under their immediate observation or experience, and do not trouble themselves about remote or doubtful consequences. If they make no profound discoveries, they do not involve themselves in gross absurdities. It is only by the help of reason and logical inference, according to Hobbes, that ?man becomes excellently wise or excellently foolish.?" »Hazlitt

"If with a stranger thou discourse, first learn, By strictest observation, to discern If he be wiser than thyself, if so, Be dumb, and rather choose by him to know; But if thyself perchance the wiser be, Then do thou speak, that he may learn by thee." »Randolph
