Abstract. The ideas have a fundamental importance for world’s destiny. Within the human civilization world of thinking, the scientific ideas represent the essence of logical structure of human mind and the truths about the human action and society that can be discovered by man. In this approach, I will argue why the scholar honest-mindedness must be his principle in life. In world’s vision about post-modernity, the only faith today is that everything is relative or otherwise stated that there is no ultimate criterion for making absolute hierarchies in order to distinguish truth from false. Thus has gradually appeared the less desired idea that ethical standards represent simple social conventions, fact that would impede the possibility of ethically validating a multitude of “alternative institutional arrangements”, including the ones contradictory with human nature and individual freedom. This study represents a plea for the virtues of logic and faith in truth and justice. Moreover, the original signification of the word “science” – scientia – is correct knowledge. Bearing this clarification in mind, the researchers would maybe become more responsible in calling any approach as being a “scientific” one and implicitly they would become more exigent with their own creations.
