What Because is for

See the shape of an argument

Because is an editor for argument visualizations — diagrams that display the logic of an argument. A visualization lays out a conclusion, the reasons offered for it, and the objections raised against it, so you can organize and navigate complex reasoning at a glance. Making the structure of an argument explicit encourages clearly articulated reasoning, and it makes intricate arguments far easier to discuss, evaluate, and teach.

Green brackets

Group supporting reasons — co-premises that work together.

Red brackets

Where it comes from

Because was built for teaching philosophy and critical thinking, in the tradition of the argument-visualization materials at philmaps.com, after the retirement of the MindMup argument-visualization service.
