Definitional consequence, elementary consequence, explicit reasoning

Definitional consequence

A conclusion that follows from what a term means.

Example:

A person is legally enslaved.

If slavery is abolished, that person is no longer legally enslaved.

The conclusion follows from the definition of abolition.

Elementary logical consequence

A conclusion that follows directly from propositions without requiring substantial historical reasoning.

Explicit reasoning

This means actually stating the reasoning that connects the propositions.

For example:

Abolition removed the legal status of slavery. This made formerly enslaved people legally capable of entering employment relationships as free persons. Consequently, they could participate in wage labor.

Why explicitly state it if evidence exists?

Because evidence and reasoning perform different functions.

Evidence tells us:

What happened?

Reasoning tells us:

Why does that evidence support this conclusion?
