Intension/extension/Mathematics/Wittgenstein: in everyday language intension and extension are not interchangeable - E.g. I hate the man in the chair - I hate Mr. Schmitz - on the other hand in mathematics: here, there is no difference between "the roots of the equation x² + 2x + 1 = 0 and "2"- in contrast difference: counting bodies ((s) extension, also writing down) is something different than to determine them with a law ((s) intension) - Wittgenstein: law and extension are completely different - ((s) Physics).
