Doth the Reality of sensible things consist in being perceived? or, is it something distinct from their being perceived, and that bears no relation to the mind?

How often must I repeat, that I know or am conscious of my own being; and that I myself am not my ideas, but somewhat else, a thinking, active principle that perceives, knows, wills, and operates about ideas?

If we admit a thing so extraordinary as the creation of this world, it should seem that we admit something strange, and odd, and new to human apprehension, beyond any other miracle whatsoever.

To be is to be perceived

What is mind? No matter. What is matter? Never mind.

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.

Few men think, yet all will have opinions.
