Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information on it.
Mankind have a great aversion to intellectual labor; but even supposing knowledge to be easily attainable, more people would be content to be ignorant than would take even a little trouble to acquire it.
Knowledge is more than equivalent to force.
In travelling, a man must carry knowledge with him, if he would bring home knowledge.
Leisure and curiosity might soon make great advances in useful knowledge, were they not diverted by minute emulation and laborious trifles.
No degree of knowledge attainable by man is able to set him above the want of hourly assistance
Knowledge always desires increase; it is like fire, which must first be kindled by some external agent, but which will afterwards propagate itself
Every error in human conduct must arise from ignorance in ourselves, either perpetual or temporary; and happen either because we do not know what is best and fittest, or because our knowledge is at the time of action not present to the mind
There is nothing so minute or inconsiderable that I would not rather know it than not know it.
