The principle of science, the definition, almost, is the following: The test of all knowledge is experiment. Experiment is the sole judge of scientific "truth. " But what is the source of knowledge? Where do the laws that are to be tested come from? Experiment, itself, helps to produce these laws, in the sense that it gives us hints. But also needed is imagination to create from these hints the great generalizations--to guess at the wonderful, simple, but very strange patterns beneath them all, and then to experiment to check again whether we have made the right guess.
Thomas Boston
It is our duty to look to God's commands, and not to His decrees; to our own duty, and not to His purposes. The decrees of God are a vast ocean, into which many possibly have curiously pried to their own horror and despair; but few or none have ever pried into them to their own profit and satisfaction.
