Abstract
As the process of formation of knowledge is a perennial concern of philosophical investigation, any systematic study of philosophy, irrespective of Eastern and Western origins, starts with a thorough assessment of our valid means of cognition. Needless to say, that our means of cognitions play a crucial role in scientific knowledge formation also. But the question of delimiting clearly the objective means of cognition from the subject of cognition continues to stimulate epistemological troubles. This has been dramatized after quantum mechanics. Founding fathers of quantum mechanics as well as the philosophers of science continued to reflect upon the enigmatic dividing line between subjective and objective. It was tried to give a purely logico-empirical objective foundation of the whole spectrum of our knowledge including the scientific. This attempt failed! Here we will give a brief overview of the problem area and the current standpoints - whether we have reached any reasonably better consensus nearly after 2000 years of debate on this.
