"One might also reason that, because the apple is not poisonous none of its constituents are. Again one would be committing the fallacy of division. Apple pips contain a form of cyanide."

Might one not safely reason, however, that none of the constituents of an apple that one actually EATS is poisonous?!

No. When I swallow a few apple seeds, it's harmless -- the amount of cyanide is so tiny that its effect is not noticable. But cyanide is, of course, poisonous in larger quantities. -- DavidCary 16:29, 24 Apr 2004 (UTC)

"A fallacy of division occurs when someone reasons logically that something that is true of a thing must also be true of its constituents."

Are there different names for

  • the fallacy of assuming something is true for *all* of its constituents
  • the fallacy of assuming something is true for *at least one* of its constituents

?
