“Reading furnishes the mind only with materials of knowledge; it is thinking that makes what we read ours.”

“The only defense against the world is a thorough knowledge of it.”

“Education begins the gentleman, but reading, good company and reflection must finish him.”

“[M]an's power, and its way of operation, [is] muchwhat the same in the material and intellectual world. For the materials in both being such as he has no power over, either to make or destroy, all that man can do, is either to unite them together, or to set them by one another, or wholly separate them.”

“Reverie is when ideas float in our mind without reflection or regard of the understanding.”

“We are like chameleons, we take our hue and the color of our moral character, from those who are around us.”

“The understanding, like the eye, whilst it makes us see and perceive all other things, takes no notice of itself: and it requires art and pains to set it at a distance and make it its own object....If by this inquiry into the nature of the understanding, I can discover the powers thereof; how far they reach; to what things they are in any degree proportionate; and where they fail us, I suppose it may be of use to prevail with the busy mind of man to be more cautious in meddling with things exceeding its comprehension; to stop when it is at the utmost extent of its tether; and to sit down in a quiet ignorance of those things which, upon examination, are found to be beyond the reach of our capacities.”
