True intelligence is seen in those who know everything about nothing, much about a few things, a little about many things, and are humble and wise enough to understand and admit the difference.
Only the ignorant think they know everything about anything.
Wisdom grows from understanding, not knowledge. A person with a little knowledge and a lot of wisdom will typically succeed whereas the person filled with knowledge untempered by wisdom will typically fail.
Good teaching always results in two things for the student, increased knowledge of the subject matter accompanied by a proportional knowledge of the degree of the student’s ignorance thereof. This is essential to lifelong learning because while the first produces the second, it is the second that motivates the first.
I am convinced of only a very few things, one of which is; as my knowledge expands, I become increasingly aware of my ignorance.
The next best thing to knowing something is knowing where to find it.
A stupid person lacks knowledge because of a limited ability to learn whereas an ignorant person lacks knowledge because of a limited desire to learn. The former has a reason for not knowing while the latter merely has an excuse. Excuses are like asses. Everybody has one and it stinks when they use it.
