Nowadays there is a tendency to claim that agnosticism and sceptical relativism are the philosophy and the basic attitude which correspond to democratic forms of political life. Those who are convinced that they know the truth and firmly adhere to it are considered unreliable from a democratic point of view, since they do not accept that truth is determined by the majority, or that it is subject to variation according to different political trends. It must be observed in this regard that if there is no ultimate truth to guide and direct political activity, then ideas and convictions can easily be manipulated for reasons of power. As history demonstrates, a democracy without values easily turns into open or thinly disguised totalitarianism.
