Logic Bent Toward Use
Logic is not the study of the syllogism but the art of directing the mind in whatever it undertakes; and thinking toward truth is a different business from thinking toward action.
For most of its history logic meant valid inference, the syllogism and its rules. Bentham sets that aside almost at once and redefines the subject far more widely: the art of directing the mind toward an end, the discipline of thinking well rather than the mere mechanics of deduction. He separates a logic of the understanding, concerned with getting at truth, from a logic of the will, concerned with acting to some purpose. Like everything he wrote, it is logic bent toward use, a set of tools for ordering thought so error has fewer places to hide, an art of practical reasoning rather than a science of proof.

Enter a dialogue
- You compare Aristotle's logic to alchemy: it failed at its aim of complete knowledge yet turned up useful discoveries. What made a failed art worth having?
- Isn't calling logic the art of directing the mind so broad that it stops being logic and becomes merely thinking well?
- You define logic as the art of directing the human mind, and through it the body, toward any aim. Why does logic reach as far as the body?
- In a debate, whoever changes his mind is felt to lose standing, and that hurts. What does that do to arguing as a way to truth?
- You separate talk meant to inform, which works on the understanding, from talk meant to persuade, which works on the passions. Which does debate really serve?
