Poincare
“To doubt everything or to believe everything are two equally convenient solutions; both dispense with the necessity of reflection.”
- Henri Poincare
Keller
Security is mostly a superstition. It does not exist in nature, nor do the children of humankind as a whole experience it. Avoiding danger is no safer than outright exposure. Life is either a daring adventure, or it is nothing at all.
- Helen Keller
