According to Karl Popper, who is the latest link in the chain of Western rationalist-empiricist debate, knowledge does not have any infallible base in either senses or reason. Taking modern science as the paradigm of human knowledge, he argues that the process of growth of scientic knowledge involves imaginative proposals of hypotheses or conjectures and their refutation on empirical grounds in a continuing series of steps. Thus, scientific knowledge continuously evolves in a series of revolutions whereby the accepted theoretic constructs (...) are falsified, therefore destroyed, and new ones accepted in their place. Experiment, as provoked and controlled stimulation of the senses, plays a critical role in this process of growth and so long as it fails to falsify the hypotheses these are provisionally accepted by the scientists.

Matter is pictured as a primitive fluid substratum having the fundamental property of fluctuating at a constant frequency. From this are derived the discrete properties of space and time, and it follows that, at the microlevel, talk of pure space and pure time involves us in ambiguities. A new interpretation of Planck's constant emerges according to which it is a quantum of matter-time combination. Thus, a quantum of matter-space combination should exist. On pursuing further the hydrodynamic model, such a constant (...) is in fact discovered as the drag-quantum of the quantum fluid. A fourth-degree differential equation is considered which, with the help of this new constant, generates spectra of frequency, mass, and fine structure constants. The theory seems to answer some important fundamental questions. (shrink)

The roots of scientific epistemology have generally been recognized in the Greeks, Aristotle and Euclid,—the former representing an empiricist trend whereas the latter representing a rationalist trend. Very little is known about classical Indian scientific epistemologies which are generally considered at least two centuries earlier than Aristotle. Inspired by the Aristotelian and Euclidean models of scientific rationality, various new models have flourished in contemporary Western thought, the prominent ones being the logical-empiricist-inductivist model (Reichenbach), the hypothet-ico-deductivist-falsificationist model (Popper), conventionalist-rationalist model (Pioncaré, (...) Duhem), dialectical-historicist model (Kuhn), and rationalist-historicist model (Lakatos, Feyerabend). While the researches in and debates about these models are still going on, it may be profitable to examine the models of scientific rationality that are presupposed in the most prominent classical Indian sciences such as Yoga, Vyākarana, Jyotisa Siddhānt, and Ayurvijñan. All these sciences have enjoyed an uninterrupted continuity ever since their origin although their evolution has suffered generally after 1200 A.D. (save Yoga) due to cultural-historical vicissitudes. (shrink)

Some of the relatively significant contributions to epistemology, in recent times, have been made by Karl Popper, Thomas Kuhn, Paul Feyerabend, and Hans Reichenbach. All these authors seem to make some radical departures from the inherited theories of knowledge. A common characteristic of their epistemologies is that they try to tackle the problem of growth of knowledge; that is to say, what is meant by saying that theories of science, as they get more and more refined, increasingly approach the truth (...) and what the nature of relationship is between the earlier theory and the more refined. later, and present theory. Philosophy in the past hardly grappled with these issues, and therefore it would be of interest to critically examine these new dimensions in Epistemology, which is the concern of this paper. (shrink)
