Philosophy
Philosophy organizes difficult questions, proposes positions, and tests the reasons for them. Its branches overlap because questions about reality, knowledge, mind, value, and society constrain one another.
A philosophical disagreement can target the question, the claim, the reasons, or the standards being used.
That makes philosophy less like a shelf of famous opinions and more like a structured space of competing explanations. The goal is not merely to collect positions, but to understand what would make one position better supported than another.
Make the question and concepts precise enough to disagree about.
Separate conclusions from the reasons intended to support them.
Use objections and counterexamples to strengthen or abandon a view.
Philosophical fields overlap because the questions overlap.
The matrix is not a rigid taxonomy. It locates each branch by the kind of subject and question it emphasizes while keeping neighboring problems visibly close.
A position is not the same thing as the reasons for it.
Map the question, claim, support, objection, and reply separately. This makes disagreement inspectable: people may reject the conclusion, one premise, the inference, or the framing of the question.
Logic studies valid inference more formally.
Philosophers use logic constantly, but Logic already has a canonical home in Formal Science. Philosophy asks what claims mean, which premises matter, what standards are appropriate, and what follows if a position is accepted; formal logic provides tools for analyzing inferential structure.
