It really depends on the level you are teaching at.

Foremost is the ability to reason.

It's amazing the pretentious nature of humanity. Life exists without you going "Hey where's my carmel macchiato". It's sad that google knew how to spell check that and I didn't.

Understand infinity and that the definition of it isn't tied to the ph level of your blood and perhaps you can understand the irrelevance of our existence. The only thing we are contributing is our perception and a rudimentary command of language we use to communicate with other

It seems this is more a discussion on the way our calories are produced than actual vegan morality. I kill animals on a regular basis and in fact i've killed people. It's an unfortunate part of life but hay I'm breathing and typing and they're not.

The fact that you are actually able to debate what kind of protein you want to consume says that me and my trigger pulling ancestors did something right; your'e welcome.

Now onto the real question is eating flesh okay; yes it is. The method of production I feel is certainly worth debate as raising a living being in a squashed in cage and using your credit card to pay some bloke to play executioner seems a little less than ethical. I'd prefer you killed your own food and owned it, recognized it for what it is and were okay with it.

There is absolutely no way to establish truth when one only will acknowledge the concepts of ones own mind. Unless we can converse with others and reach a conclusion then we are idiots. Who cares the method of recording.

Is there something about philosophy which invites or attracts a sort of pretense — Sapientia

Every question already has an answer but really just seeks validation. most ask questions with an answer in mind but seek validation for the equation.

s there something about it which opens up for debate that which we already know? — Sapientia

We wouldn't ask about something which we were sure unless we sought to define the strengths and weaknesses of said thing.

Is everything really a matter of personal opinion — Sapientia

No. Somethings unknown to fact are open to interpretation. Sanity isn't a matter of perception it's a matter of reality. Reality is determined by provable facts. Facts proven outside of the mind and in the physical realm or the intellectual realm by a predetermined set of values.
