However, both Bomb#20 and Angra Mainuy at one point started to play teacher (repeated below) by authoritatively asserting validity to posters who had commented that the argument was not valid, and this on the basis that validity was a consequence of the definition of validity. This showed clearly that both thought the word "validity" means

*mathematical logic* validity. Yet, my question was about validity without any reference to mathematical logic. Thus, the debate turned on to whether there was such a thing as a notion of logical validity outside mathematical logic. Given the answers by most posters, clearly there is, but our specialists of mathematical logic here disputed this. So, somewhere, I asked my question about the justification of the mathematical definition of logical validity/ Is there a justification that it is correct? Because if not, then people should abstain from pretending there's just the mathematical logic's notion of validity.
