A rational morality would imply perfect self-knowledge, so that no congenial good should be needlessly missed—least of all practical reason or justice itself; so that no good congenial to other creatures would be needlessly taken from them.

Context

“A truly rational morality, or social regimen, has never existed in the world and is hardly to be looked for. What guides men and nations in their practice is always some partial interest or some partial disillusion. A rational morality would imply perfect self-knowledge, so that no congenial good should be needlessly missed—least of all practical reason or justice itself; so that no good congenial to other creatures would be needlessly taken from them. The total value which everything had from the agent's point of view would need to be determined and felt efficaciously; and, among other things, the total value which this point of view, with the conduct it justified, would have for every foreign interest which it affected.” source
