Let us work without theorizing, tis the only way to make life endurable. Voltaire
What is the use of theorizing as to wherein lies the charm that moves us? Alfred de Vigny
Natural objects, for example, must be experienced before any theorizing about them can occur. Edmund Husserl
I soon became convinced... that all the theorizing would be empty brain exercise and therefore a waste of time unless one first ascertained what the population of the universe really consists of. Fritz Zwicky
