"To teach is to learn twice."
"The more that you read, the more things you will know. The more that you learn, the more places you'll go."
"All of life is a constant education."
"Upon the subject of education, not presuming to dictate any plan or system respecting it, I can only say that I view it as the most important subject which we as a people may be engaged in. That everyone may receive at least a moderate education appears to be an objective of vital importance."
