He taught, as we saw, and Godwin developed the view in his own way, that the natures and characters of men are moulded entirely by their environment--not physical, but intellectual and moral environment, and therefore can be indefinitely modified.

A man is born into the world without innate tendencies.

His conduct depends on his opinions.

Alter men's opinions and they will act differently.

Make their opinions conformable to justice and benevolence, and you will have a just and benevolent society.
