The universe is unfolding as it should.
Observations always involve theory.
The great spirals... apparently lie outside our stellar system.
All nature is a vast symbolism: Every material fact has sheathed within it a spiritual truth.
A scientist naturally and inevitably ... mulls over the data and guesses at a solution. He proceeds to testing of the guess by new data-predicting the consequences of the guess and then dispassionately inquiring whether or not the predictions are verified.
Science is the one human activity that is truly progressive. The body of positive knowledge is transmitted from generation to generation.
