This essay is part of the studies that I do which are related to several subjects and also refer to the project of creating an electronic platform which among others things will be protecting its users from fake news. The achievement of every goal requires also valid information which is transformed to knowledge. The present essay is the first part of two essays related to the evaluation of truth and sets a philosophical basis on what truth is. (greek below)
We begin with the definition of truth. We will not use the etymology of the greek word for truth which leads to its definition as non oblivion. The definition will be closer to that of the notion of validity. The first thing that we should bear in mind is that there are no facts; there are only interpretations of facts based on deliberate axioms. If we observe a flower on the road, we have no proof whatsoever that what we see actually exists, we axiomatize that it exists. To be precise we axiomatize the existence of our senses. It is by interpreting our sense that we conclude that the flower of the previous example is there. Furthermore even if we accept that there are objects external to us, since we get on touch with them only through our senses, this means that when we refer to reality we actually refer to the projection of reality on our senses and not to the objects themselves.
