### Aristotle - The Organon ANALYTICA PRIORIA Book 2 Part 18

## A false argument depends on its first false statement

1.
A false argument depends on the first false statement in it.
Every
syllogism is made out of two or more premisses. If then the false
conclusion is drawn from two premisses, one or both of them must be
false: for (as we proved) a false syllogism cannot be drawn from two
premisses. But if the premisses are more than two, e.g. if C is
established through A and B, and these through D, E, F, and G, one
of these higher propositions must be false, and on this the argument
depends: for A and B are inferred by means of D, E, F, and G.
Therefore the conclusion and the error results from one of them.
