The great extension of our experience in recent years has brought light to the insufficiency of our simple mechanical conceptions and, as a consequence, has shaken the foundation on which the customary interpretation of observation was based.

One has to stress once again, that the mechanical world view and psychophysical interpretation accompanying it are based not on the instructions of the philosophizing mind, but on the clear and accurate facts discovered by experiment and observation; and in the cases of non-correspondence (very rare, fortunately) between the requirements of the mind and the facts, reason must adjust to the facts, and not vice versa.
Yakov Frenkel
Three conceptions are perpetually turning up at every point in every theory of logic, and in the most rounded systems they occur in connection with one another. They are conceptions so very broad and consequently indefinite that they are hard to seize and may be easily overlooked. I call them the conceptions of First, Second, Third. First is the conception of being or existing independent of anything else. Second is the conception of being relative to, the conception of reaction with, something else. Third is the conception of mediation, whereby a first and second are brought into relation.
Charles Sanders Peirce
My main theme is the extension of the nervous system in the electric age, and thus, the complete break with five thousand years of mechanical technology. This I state over and over again. I do not say whether it is a good or bad thing. To do so would be meaningless and arrogant.
Marshall McLuhan
My choice of colours does not rest on any scientific theory:it is based on observation,on sensitivity,on felt experience.
Henri Matisse
The great object of all knowledge is to enlarge and purify the soul, to fill the mind with noble contemplations, to furnish a refined pleasure, and to lead our feeble reason from the works of nature up to its great Author and Sustainer. Considering this as the ultimate end of science, no branch of it can surely claim precedence of Astronomy. No other science furnishes such a palpable embodiment of the abstractions which lie at the foundation of our intellectual system; the great ideas of time, and space, and extension, and magnitude, and number, and motion, and power. How grand the conception of the ages on ages required for several of the secular equations of the solar system; of distances from which the light of a fixed star would not reach us in twenty millions of years, of magnitudes compared with which the earth is but a foot-ball; of starry hosts—suns like our own—numberless as the sands on the shore; of worlds and systems shooting through the infinite spaces
