“Nature does nothing in vain, and in the use of means to her goals she is not prodigal.”
Third Thesis
Idea for a Universal History from a Cosmopolitan Point of View (1784)
Context: Nature does nothing in vain, and in the use of means to her goals she is not prodigal. Her giving to man reason and the freedom of the will which depends upon it is clear indication of her purpose. Man accordingly was not to be guided by instinct, not nurtured and instructed with ready-made knowledge; rather, he should bring forth everything out of his own resources.
The Days of My Life : An Autobiography (1989), p. 212
Context: My first TV series on demonstrations in physics — titled Why Is It So? were now seen and heard over the land. The mail was massive. The academics were a special triumph for me. They charged me with being superficial and trivial. If I had done what they wanted my programs would be as dull as their classes! I knew my purpose well and clear: to show how Nature behaves without cluttering its beauty with abtruse mathematics. Why cloud the charm of a Chladni plate with a Bessel function?
