Accurate knowledge is the basis of correct opinions; the want of it makes the opinions of most people of little value.

It is not so important to know everything as to know the exact value of everything, to appreciate what we learn, and to arrange what we know.

Knowledge always desires increase; it is like fire, which must first be kindled by some external agent, but which will afterward propagate it.

What is not fully understood is not possessed.

Knowledge is the eye of desire and can become the pilot of the soul.

Learning is acquired by reading books, but the much more necessary learning, the knowledge of the world, is only to be acquired by reading men, and studying all the various facets of them.

Real knowledge, like everything else of value, is not to be obtained easily. It must be worked for, studied for, thought for, and, more that all, must be prayed for.

Friendship is a living thing that lasts only as long as it is nourished with kindness, empathy and understanding.

My feeling is that there is nothing in life but refraining from hurting others, and comforting those who are sad.

One can pay back the loan of gold, but one dies forever in debt to those who are kind.
