In the sciences, the authority of thousands of opinions is not worth as much as one tiny spark of reason in an individual man.

Two truths cannot contradict one another.

Scripture is a book about going to Heaven. It's not a book about how the heavens go.

Where the senses fail us, reason must step in.

In questions of science, the authority of a thousand is not worth the humble reasoning of a single individual.

The prohibition of science would be contrary to the Bible, which in hundreds of places teaches us how the greatness and the glory of God shine forth marvelously in all His works, and is to be read above all in the open book of the heavens.
