Our goal is to investigate the biological correlates of the first-person experience of time or phenomenal time. ‘Time’ differs in various domains, such as (i) physical time (e.g., clock time), (ii) biological time, such as the suprachiasmatic nucleus, and (iii) the perceptual rate of time. One psychophysical-measure of the perceptual rate is the critical flicker frequency (CFF), in which a flashing light is perceived as unchanging. Focusing on the inability to detect change, as in CFF, may give us insight into (...) phenomenal time. CFF varies from 24 Hz for dim light and 60 Hz in bright light and is lower for colored lights. We propose that problem of the phenomenal time can be addressed using two contrasting but complementary approaches (inability to detect changes vs. ability to detect changes): (1) The soliton-catalytic model that entails invariant quantum coherent state for temporal frequencies (TFs) >= CFF, where flickering light is perceived as unchanging, similar to a Bose-Einstein condensate (BEC). (2) Temporal frequency tuned mechanisms model, which starts with ability to detect changes for TFs < CFF and then their sensitivities decreases to zero at CFF. For a subject who has CFF of 60 Hz, the duration of one cycle or time-period of the flickering light is approximately 16.7 ms. Phenomenal time may be quantized into ‘subjective occasions of experience’ (SE), which arise out of the interaction of the individual with situation (environment). Pioneering work examining the complex interaction of neurons suggests the possibility that macroscopic quantum states similar to a BEC may also occur in the brain (Davia, 2006; Freeman & Vitiello, 2006; Georgiev, 2004; Vimal & Davia, 2008) .

Time’s arrow is necessary for progress from a past that has already happened to a future that is only potential until creatively determined in the present. But time’s arrow is unnecessary in Einstein’s so-called block universe, so there is no creative unfolding in an actual present. How can there be an actual present when there is no universal moment of simultaneity? Events in various places will have different presents according to the position, velocity, and nature of the perceiver. Standing against (...) this view is traditional common sense since we normally experience time’s arrow as reality and the present as our place in the stream of consciousness, but we err to imagine we are living in the actual present. The present of our daily experience is actually a specious present, according to E. Robert Kelly (later popularized by William James), or duration, according to Henri Bergson, an habitus, as elucidated by Kerby (1991), or, simply, the psychological present (Adams, 2010) – all terms indicating that our experienced present so consists of the past overlapping into the future that any potential for acting from the creative moment is crowded out. Yet, for philosophers of process from Herakleitos onward, it is the philosophies of change or process that treat time’s arrow and the creative fire of the actual present as realities. In this essay, I examine the most well known but possibly least understood process cosmology of Alfred North Whitehead to seek out this elusive but actual present. In doing so, I will also ask if process philosophy is itself an example of the creative imagination and if this relates to doing science. I conclude Whitehead's process philosophy falls short of allowing for the actual creative spontaneity of a dynamic (eternal) present. (shrink)

While the logical reconstruction of empirical theories is, in principle, no longer a matter of dispute, the possibility and, furthermore, the procedure of constructing ab initio such theories are hardly debated upon, although this might be conducive to the advancement, above all, of sciences of a pre-paradigmatic status. Eight steps are here proposed for the constructive development of an explanatory empirical theory in a strictly scientific sense, the development starting with a construction of the theory's set of partial potential models (...) ${\rm M}_{{\rm pp}}$ and ending up in a characterization of its range of intended applications I. The set of partial potential models is gained by way of genetic reduction of present-day practical, i. e. pre-theoretical, notions, which denote observable facts to be explained, to some possible notion of an elementary historical practice. This elementary practical notion, which must be conceived as a general notion of a formerly given elementary social practice, has afterwards to be developed into some general notion for all the phenomena to be presently explained, by way of reconstructing the historical emergence of the present field of research. The elementary practical notion also forms the basis for the generation of the explaining so-called t-theoretical terms of the theory. Their development, however, presupposes a 'political' decision of the scientist to work in favour of the perfection of certain practically relevant capacities, which decision also determines the domain of discourse for the set of partial potential models of the theory and links its explaining terms to the terms denoting the facts to be explained. A set Iₒ of successful applications of the as yet not completed theory and respective special laws, making up the success of such applications, render possible the full axiomatization of the theory as well as the characterization of the range of its intended applications.

A Constructivist Foundation of the Objects of Scientific Empirical Theories. The following considerations are guided by the assumption that the objects of any scientific empirical theory are constructs as well as the theories themselves, the construction of these object-constructs being fundamentally dependent on the theories' functioning in the provision of practically relevant empirical explanations. The relevance of these explanations consists in their contribution to the improvement of at least one practical capacity through enabling the invention of at least one improving (...) kind of practical actions. In an excursus on the origination and the development of the notion of theory within human history the view is held, in contrast to Aristotle, that theorization has always aimed at practical relevance, however in a broader sense of "practical" than that in which Aristotle uses the term "πρακτικός", and that only the practical functions of theory-construction have changed over the times, and their object-constructs correspondingly. The latest form of theory with the above-mentioned function in the development of social practice is the scientific explanatory empirical theory with the descriptive empirical theory now no longer fulfilling a practical function of its own, but only a service-function of data acquisition for the explanatory theory. The object-constructs of strictly scientific empirical theories in the sense of explanatory theories for the improvement of practical capacities are here considered to be empirical quasi-actions, those of the dependent descriptive empirical theories either quasi-instruments or quasi-products or quasi-materials of the respective kind of quasi-actions of the explanatory theory. The empirical quasi-action is here conceived as the latest in a sequence of developing object-constructs that have resulted from different and successively more effective attempts at better survival of human beings and even from prehuman stages of evolution. The author envisages a differentiation of empirical quasi-actions into further sub-categories to provide the conceptual bases for the construction of objects of new kinds of scientific explanatory empirical theories that might become practically relevant for the improvement of new kinds of practical capacities to be preferably improved for the advancement of social practice: Beside the already relevant category of empirical processes are here proposed the further categories of empirical originations of meaning and of empirical originations of practical actions as conceptual bases for object-constructs of future scientific empirical theories.
