If I negate "all", it becomes "not all." But doesn't "not all" imply two distinct possibilities, namely, "some" and "none"? If I negate the statement "all turtles are slow" as "it is not the case that all turtles are slow." Can't it either mean "some turtles are not slow" (there is at least one turtle that is NOT slow out of all the turtles on this earth) or "none of the turtles are slow" (they are ALL FAST AND FURIOUS BEASTS.) When I negate a conditional statement in LSAT, should I be mindful of these two distinct possibilities?
Any reply is welcome.
Thanks.
