All men have opinions, but few think.

This perceiving, active being is what I call mind, spirit, soul, or myself. By which words I do not denote any one of my ideas, but a thing entirely distinct from them, wherein they exist, or, which is the same thing, whereby they are perceived; for the existence of an idea consists in being perceived.

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?

Few men think, yet all will have opinions.

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?
