False Gods And False Satans I think in society there maybe the approach that what is useful, is therefore the truth....as sort of utilitarian approach to truth.
But what is useful for one set of people won't always be useful for another set of people.
And as I said in another thread, there doesn't seem to be a way to determine an object truth*, so truth will always be subjective, and people can use this idea to arrive at my first statement, and just go along with the idea that what is useful is truth, although there are ways to arrive at a more objective truth by looking at evidence, this can be inconvenient for some, and they therefore might say that what isn't useful, or is indeed counter to their group, is therefore no the truth...which you see with climate change deniers.
* and even using terms like 'objective reality' and 'objective truth' these are terms that risk being see as objective statements, and if one is claiming that there can be no objective reality, then one can't make objective claims about it.....so what we are often left with is accepting ideas as useful, or ideas which aren't useful, as statements of truth.....and people often base their thinking on what is useful to them, their self interest...so often opt for ideas that are useful for them and call them truths..
It would be far more honest for most people to say they base their philosophies on the bases of what is useful to them personally, what is useful for their own survival, and not try to claim these positions are based upon some vague definition of truth.
