# Deduction

General to specific logic

Layer: Mind · Category: Reasoning

## Mechanism

Moving from general rules ([Axiom](https://mindscape.pages.dev/bootstrap/Axiom.md)) to specific conclusions. If premises are true, the conclusion MUST be true. (All men are mortal -> Socrates is a man -> Socrates is mortal).

## Invariants

- Truth Preservation: If premises are true, conclusion MUST be true.
- Validity: The argument structure follows formal logic rules.

## Preconditions

- Premises are accepted as true

## Postconditions

- Conclusion is logically necessary

## Failure modes
