Umm... new to site & so new Q.
Had to set up a new space to ask such a Question on Quora recently. Called the Environment of Philosophy Space where there Q. & Answers in reality explaining the bad shape of current & past taught philosophy. Each one of us has had little responsibility for that nevertheless we can and should have some knowledgeable responsibility to understand a better need now for such an environment. An ENVIRONMENT OF (better) SUSTAINABLE relevant knowledge... or objective philosophy knowledge & it's wide-ranging learned BEHAVIOUR, that may be otherwise called "Critically rational knowledge".
P.s. talk of "truth" is and should be off-loaded when discussing Sustainable philosophy knowledge. Why? Because under the banner of "knowledge" or even "NEW knowledge" most if not all of the countless silly wranglings that occur in discussions here and at other sites are not needed if we need to learn some type of SUSTAINABLE behaviour knowledge. And this is an avoidance preference which can bring more benefit to subsequent discussions, discussions which we all have-to-have but should not hamper the getaway to some new environment of learning so to speak.. which we can all participate in, appreciate of and of course understand (with some help from interested others!).
What is Sustainable philosophy of the Objective kind ?
