“For every theory there has to be counterevidence--otherwise science wouldn't progress.”

“Progress in science is governed by the laws of repulsion, every step forward is made by refutation of prevalent errors and false theories. Forward steps in art are governed by the law of attraction, are the result of imitation of and admiration for beloved predecessors.”

“[we see that] science is eminently perfectible, and that each theory has constantly to give way to a fresh one.”

“Every poet has trembled on the verge of science.”

“Science requires both observation and comprehension. Without observation there are no facts to be comprehended; without comprehension science is mere documentation. The basis for comprehension is theory, and the language of theoretical science is mathematics. Theory is constructed on a foundation of hypothesis; the fewer the hypotheses needed to explain existing observations and predict new phenomena, the more ‘elegant’ the theory”

“Everything on the earth has a purpose, every disease an herb to cure it, and every person a mission. This is the Indian theory of existence.”
