The paradox of tolerance

Yes, if Nazis (or the Borg) invade our space with the intent to 'assimilate' us (turn us into slaves), then by all means photon torpedoes, full spread. And/or incite species 8472 to kick their ass.

The paradox of tolerance or a performative contradiction only applies in limited and obviously inadequate dichotomous logic with the axiom of the exclude middle. Fortunately cogsci has come a long way since then and proven its erroneous assumption.

E.g.,
the law of the excluded middle arises from the container image schema. Yes, using that schema one can make valid inferences to the excluded middle. But that is just one of a plethora of image schema, each with their own valid inference structures, many of which include rather than exclude a middle ground.

Basic categories are in fact in the middle of classical hierarchical taxonomies showing all kinds of middle ground between dichotomous logic. The problem arises when someone (or group or philosophy) takes one image schema, assume that it reflects reality in toto, and puts everything else in those boxes.
