“I am old and weak and bruised (with rupture and colic), and lameness on both feet.”

“It was an act of despair, to sacrifice physics for the sake of finding an explanation.”

“Natural selection acts solely by the preservation and accumulation of small inherited modifications, each profitable to the preserved being.”

Mike's Takeaway:

A clear thinker does not believe harder just because an idea feels meaningful, familiar, or comforting. Belief should be proportional to evidence, logic, testing, and trustworthy guidance. Think well by letting confidence grow only when support earns it.

In 1739, when Hume wrote:

“A wise man proportions his belief to the evidence.”

Hume was not saying smart people believe nothing. He is not telling us to become frozen skeptics, afraid to trust anything. He is saying belief should be earned. Let confidence rise, but make it rise for a reason.

That is the science-first spirit. You do not commit first and defend later. You let evidence, logic, testing, and good authority do their work. Some ideas deserve strong belief. Some deserve light belief. Some deserve no belief yet.

That is believing well: proportion your confidence to the support.
