These are all certainly interesting thoughts, and i cannot, though id wish to do so, reply to all of them at once.
I have indeed heard the phrase “there is no such thing as truth”, and it has always been a shaky question for me.
It is one of the biggest reasons i got into philosophy, and i think one of the biggest reasons that anyone does.
I got into philosophy to get as close to absolute truth as possible, and find if absolute truth exists.
I also got into philosophy to discover what is real, and to figure out what really exists, and to figure out if the material world truly exists or not, or if it even matters.
My mentor once told me there is no way to achieve absolute truth, that it is much like absolute zero in science terms.
I often ponder the truthfullness of mere statements. If i say something, and i certainly believe it to be true, i will say that it is true. If i say i milked my goat correctly to full capacity, i will believe it to be true by my standards, but the goat with sore teats may disagree. Something is often true in ones mind, and not true to others.
That brings up what i call social truths: what the public says is true. The general thought in public is that murder, in any shape or form, is entirely immoral. (sorry to bring up morality) whereas, some may say that it in some circumstances, it is completely acceptable, if not completely moral.
which brings up circumstantial truth.
I look up now, and the sky appears to me to be blue. Often people say " The sky is blue and the grass is green"
but i like to think, “Is the sky really blue? and if it is, it certainly wont stay blue! when rain comes, the sky is gray. so why not say the sky is gray? and grass is not always green, come cold weather the grass dies and becomes brown. so is grass not brown?” to me, truth is as relative as “Toe-may-toe, toe-mah-toe”. shoot away, fellas
