The Categorical Imperative: what this star will be

Act only as you would have everyone always act.

By Constellate · 9 September 2026 · the short form

The Categorical Imperative is a star on the Constellate sky: placed by meaning, named, and connected to the stars around it. This is the short form of its post: the line it carries, the area we colour Philosophy, and what stands beside it today.

The line it carries on the sky: Act only as you would have everyone always act.

What stands beside it

The stars nearest to it are Roles and Duties, The Rule of Law, The Trolley Problem and Utilitarianism. When The Categorical Imperative opens, the conversation will land it among them, with a line drawn to each idea it touches.
