Logical Moralism

The practice of using formal logic and logical reasoning as a basis for moral judgment—condemning positions as "illogical" as if logical consistency were the highest ethical value, or deriving moral conclusions from logical premises as if ought could be deduced from is. Logical moralism treats moral disagreements as failures of reasoning, assuming that if everyone just thought clearly enough, they'd arrive at the same ethical conclusions. It's the philosopher who thinks teaching logic will eliminate prejudice; the debater who treats every moral question as soluble through syllogism; the rationalist who believes irrationality is the source of all evil. Logical moralism mistakes one tool of thought for the whole of moral wisdom.

Example: "He couldn't engage with her moral concerns—he just kept pointing out where her arguments were 'illogical,' as if logical consistency was the only thing that mattered. Pure Logical Moralism, mistaking reasoning for righteousness."
