Q

Masked Man Fallacy

A

masked-man fallacy (aka the intensional fallacy and the epistemic fallacy) is committed when one makes an illicit use of Leibniz’s law in an argument.

Leibniz’s law states that, if one object has a certain property, while another object does not have the same property, the two objects cannot be identical.

Basically confused / bad use of Leibniz’ Law On the Identity of Indiscernibles.

So:
1) I know there is a masked man in the room
2) I know my dad is in the room
C) my dad is not the masked man
