“I have never let my schooling interfere with my education.”

“The opinions that are held with passion are always those for which no good ground exists; indeed the passion is the measure of the holders lack of rational conviction. Opinions in politics and religion are almost always held passionately.”
― Bertrand Russell, Sceptical Essays

“The only way of discovering the limits of the possible is to venture a little way past them into the impossible.”
― Arthur C. Clarke

“I can live with doubt and uncertainty and not knowing. I think it is much more interesting to live not knowing than to have answers that might be wrong. If we will only allow that, as we progress, we remain unsure, we will leave opportunities for alternatives. We will not become enthusiastic for the fact, the knowledge, the absolute truth of the day, but remain always uncertain … In order to make progress, one must leave the door to the unknown ajar.”
― Richard P. Feynman
