George Berkeley

George Berkeley
George Berkeley— known as Bishop Berkeley— was an Anglo-Irish philosopher whose primary achievement was the advancement of a theory he called "immaterialism". This theory denies the existence of material substance and instead contends that familiar objects like tables and chairs are only ideas in the minds of perceivers, and as a result cannot exist without being perceived. Berkeley is also known for his critique of abstraction, an important premise in his argument for immaterialism...

Nothing can be plainer, than that the motions, changes, decays, and dissolutions, which we hourly see befall natural bodies (and which is what we mean by the course of nature), cannot possibly affect an active, simple, uncompounded substance: such a being therefore is indissoluble by the force of nature, that is to say, the soul of man is naturally immortal.
In short, if there were external bodies, it is impossible we should ever come to know it; and if there were not, we might have the very same reasons to think there were that we have now.
It would much conduce to the public benefit, if, instead of discouraging free-thinking, there was erected in the midst of this free country a dianoetic academy, or seminary for free-thinkers, provided with retired chambers, and galleries, and shady walks and groves, where, after seven years spent in silence and meditation, a man might commence a genuine free-thinker, and from that time forward, have license to think what he pleased, and a badge to distinguish him from counterfeits.
All that stock of arguments [the skeptics] produce to depreciate our faculties, and make mankind appear ignorant and low, are drawn principally from this head, to wit, that we are under an invincible blindness as to the true and real nature of things.
I am apt to think, if we knew what it was to be an angel for one hour, we should return to this world, though it were to sit on the brightest throne in it, with vastly more loathing and reluctance than we would now descend into a loathsome dungeon or sepulchre.
It is a mistake, to think the same thing affects both sight and touch. If the same angle or square, which is the object of touch,be also the object of vision, what should hinder the blind man, at first sight, from knowing it?
If what you mean by the word "matter" be only the unknown support of unknown qualities, it is no matter whether there is such a thing or no, since it no way concerns us; and I do not see the advantage there is in disputing about what we know not what, and we know not why.
The method of Fluxions is the general key by help whereof the modern mathematicians unlock the secrets of Geometry, and consequently of Nature.
The table I write on I say exists ... meaning thereby that if I was in my study I might perceive it, or that some other spirit actually does perceive it.
Make a point never go clear, it is great odds that a man whose habits and the bent of whose mind lie a contrary way, shall be unable to comprehend it. So weak a thing is reason in competition with inclination.
The fawning courtier and the surly squire often mean the same thing,--each his own interest.
I imagine that thinking is the great desideratum of the present age; and the cause of whatever is done amiss may justly be reckoned the general neglect of education in those who need it most, the people of fashion. What can be expected where those who have the most influence have the least sense, and those who are sure to be followed set the worst examples?
Of all men living [priests] are our greatest enemies. If it were possible, they would extinguish the very light of nature, turn the world into a dungeon, and keep mankind for ever in chains and darkness.
I might as well doubt of my own being, as of the being of those things I actually see and feel.
