Question

Use Euler circles to check the validity of the argument.
All scientists are eccentrics.
All eccentrics are kind.
Therefore, all scientists are kind.

How do I find out if this is valid or not?

Answer 1

Here is a circle to represent the set of all kind people

Answer 2

Inside it, draw another circle to represent the set of eccentric people. This new circle is completely contained in the previous one because "All eccentrics are kind"

Answer 3

then draw another circle inside the one we just drew to represent the set of scientists

this is completely contained in the eccentric circle because " All scientists are eccentrics"

Answer 4

so we can see that "Therefore, all scientists are kind. " is a true statement because every scientist is also in the "kind people" circle

Answer 5

ohhhh
