Quote of the Day – Immanuel Kant


” When Galileo caused balls, the weights of which he had previously determined, to roll down an inclined plane; when Torricelli made air carry a weight which he had calculated beforehand to be equal to that of a definite volume of water; or in more recent times, when Stahl changed metal
into oxides, and oxides back into metal, by withdrawing something and then restoring it, a light broke upon all students of nature. They learned that reason has insight only into that which reason produces after a plan of its own; that reason must not allow itself to be constrained, as it were, by nature’s reins, but must itself show the way… thereby constraining nature to give answer to questions of reason’s own determining. Accidental observations, made in obedience to no previously thought-out plan, can never be made to yield a necessary law, which reason alone is concerned to discover… Reason must not approach nature in the character of a pupil who listens to everything the teacher has to say, but as an appointed judge who compels the witness to answer questions that he himself has formulated. ”
