Many of the things that you have been taught were at one time the radical ideas of individuals who had the courage to believe what their own hearts and minds told them was true, rather than accept the common beliefs of their day. God may have been waiting centuries for someone ignorant enough of the impossible to do that very thing. Our greatest natural resource is the minds of our children. Just as eating against one's will is injurious to health, so studying without a liking for it spoils the memory, and it retains nothing it takes in. The idea that the majority of students attend a university for an education independent of the degree and grades is a hypocrisy everyone is happier not to expose.
Common sense is the collection of prejudices acquired by age eighteen.
The secret of the man who is universally interesting is that he is universally interested. We must never cease from exploration. And the end of all our exploring will be to arrive where we began and to know the place for the first time. All this is put in your hands as your inheritance in order that you may receive it, honor it, add to it, and one day faithfully hand it on to your children. Too often we give our children answers to remember rather than problems to solve.
