- inference in which the conclusion is of no greater generality than the premises
- inference in which the conclusion is just as certain as the premises
Deductive reasoning is the type of reasoning that proceeds from general principles or premises to derive particular information.
Deductive logic
Deductive reasoning is supported by deductive logic (which is not quite the same thing).
For example:
- All apples are fruit.
- All fruits grow on trees.
- Therefore all apples grow on trees.
Or
- All apples are fruit.
- Some apples are red.
- Therefore some fruit is red.
Intuitively, one might deny the major premise and hence the conclusion; yet anyone accepting the premises accepts the conclusion.
