Some vs. Some not

If I know that A-some-B, isn't it also true that A-some not-B?

Hi @devinjax14,

Thanks for the question! While it may seem like this way in ordinary language use sometimes, we actually can’t conclude that this is the case. We can’t conclude from

A <—some—> B

that

A <—some—> ~B

Remember that “some” can mean “all” on the LSAT, since “some” just means “at least one.” So you could say “all dogs are mammals,” but that also means that “some dogs are mammals,” just in this case the “some dogs” happen to be “all the dogs.” So then it wouldn’t be true that some dogs aren’t mammals.

Hope this helps! Feel free to ask any other questions that you might have.
