"Teaching should be such that what is offered is perceived as a valuable gift and not as hard duty. Never regard study as duty but as the enviable opportunity to learn to know the liberating influence of beauty in the realm of the spirit for your own personal joy and to the profit of the community to which your later work belongs."

"Gravitation is not responsible for people falling in love."

"It is harder to crack prejudice than an atom."

"Small is the number of them that see with their own eyes and feel with their own hearts."

"Wisdom is not a product of schooling but of the lifelong attempt to acquire it."
