Webster 1913 Edition
συλλογισμόσa reckoning all together, a reasoning, syllogism, fr.
συλλογίζεσθαιto reckon all together, to bring at once before the mind, to infer, conclude;
σύνwith, together +
λογίζεσθαιto reckon, to conclude by reasoning. See
The regular logical form of every argument, consisting of three propositions, of which the first two are called the premises, and the last, the conclusion. The conclusion necessarily follows from the premises; so that, if these are true, the conclusion must be true, and the argument amounts to demonstration;
as in the following example:Every virtue is laudable; Kindness is a virtue; Therefore kindness is laudable.These propositions are denominated respectively the major premise, the minor premise, and the conclusion .
☞ If the premises are not true and the syllogism is regular, the reasoning is valid, and the conclusion, whether true or false, is correctly derived.
Webster 1828 Edition
A form or reasoning or argument, consisting of three propositions, of which the two first are called the premises, and the last the conclusion. In this argument, the conclusion necessarily follows from the premises; so that if the two first propositions are true, the conclusion must be true, and the argument amounts to demonstration. Thus,
A plant has not the power of locomotion;
An oak is a plant;
Therefore an oak has not the power of locomotion.
These propositions are denominated the major, the minor, and the conclusion.
