A philosophy degree doesn't meant shite to me.
That is just to say that I have some familairity with the study of ontology. I think you might have read too much into the statement, lol.
All you people learn to do it argue properly, with logic.
It is surprising to think, but formal logic generally only allows one to prove in explicit terms what they already knew in a more colloquial sense. There is indeed an accepted connection between many words and phrases and first order logical symbols and connectives, but most functional phrases in English actually don't have fixed logical equivalents. "Everyone loves a woman", for instance. That phrase is held to have at least six possible readings, including the ideas that every person loves a different woman; every person loves any woman; there exists a woman that all people in the world love; for every person in the world, there exists one, and only one specific woman that that person loves, and none of them love the same woman; should there be a given woman, it can be shown that all people love that woman, and at least one other reading I am not thinking of. The words themselves can be fixed individually as logical constants, but somehow the whole thing is much more ambiguous.
I am just trying to point out that you can try to keep your reasoning consistent with logic, but once you step out of the narrow world of first order logical statements, there is no way to ensure that there is a one to one relationship between your phrasing and possible logical interpretations.
And you can add to this the notion that while it is possible to reach sound conclusions if your premises are known to be certain, there are very few things that can arguably be known for certain in this world, and thus very few conclusions that can be argued to be sound. You can try to get past this problem, arguing that there are things in plain sight everyone knows to be true, but amazingly, you will find that almost no standard of proof is great enough to claim to know circumstantial things about the world. I am not saying that one can't know anything, but rather that you might be disappointed about the things that are agreed to be provable. Mostly stuff about numbers, really

And Descartes and others doubted even these....
