Time & Perspective Quote by Charles Darwin

"A moral being is one who is capable of reflecting on his past actions and their motives - of approving of some and disapproving of others"

About this Quote

Morality, for Darwin, isn’t a thunderbolt from heaven; it’s a cognitive upgrade. He frames the moral being as a creature with a rearview mirror: able to replay yesterday’s choices, interrogate the motives behind them, and then render judgment on the self. The sting is in the ordinariness of the mechanism. No angels, no commandments, no metaphysical tribunal - just reflection, memory, and the uncomfortable capacity to feel satisfied or ashamed.

The intent is quietly radical. By defining morality as self-scrutiny rather than obedience, Darwin relocates ethics from external authority to an internal process that can be studied, compared across species, and explained through development. This lines up with his larger project in The Descent of Man: human exceptionalism gets trimmed down to differences of degree. Moral life becomes continuous with social instincts and intelligence, not a separate substance injected into us.

The subtext is also a warning. If morality depends on reflecting on motives, then moral failure isn’t just doing harm; it’s refusing to look. The definition privileges psychological honesty over performative virtue. It also anticipates a modern discomfort: motives are messy, self-knowledge is partial, and memory is biased. Darwin’s moral being is not a saint; it’s an animal capable of self-critique - and therefore capable of guilt, rationalization, growth, and hypocrisy.

In Victorian context, that’s evolutionary theory doing cultural work: dethroning moral certainty while offering a spare, sturdy replacement built from human (and animal) faculties rather than divine decree.
