[filed under theme 2. Reason / F. Fallacies / 6. Fallacy of Division ]

Full Idea

The fallacy of division is the claim that what is true of a set must therefore be true of its members.

Gist of Idea

What is true of a set is also true of its members

Source

PG (Db (ideas) [2031])


A Reaction

Clearly a fallacy, but if you only accept sets which are rational, then there is always a reason why a particular is a member of a set, and you can infer facts about particulars from the nature of the set
