Reflections in Cosmology 10: Time and Its Arrow

Hi again. I think it was in the sixth grade when I opened up a Colliers’ Encyclopedia (dated 1920) and read about Einstein’s theories on time. Ever since, time for me has been the most amazing thing. (Oh, by the way, just google my name if you want to find my blog.)
Time may be described on three levels. Theoretical physics (both quantum mechanics and relativity theory) measures time in its physical aspect, that is, “the t-coordinate is an undifferentiated continuum, and, if this coordinate is ‘taken for real’ as has been the tendency among many scientists and philosophers, the familiar distinction between past, present and future, so important in human affairs, comes to be regarded as a mere peculiarity of consciousness.” [Kenneth G. Denbigh, Three Concepts of Time, 1981, p. 4.] We also encounter the concept of non-reversible time in the physical sciences. In thermodynamics and in the biological sciences the arrow of time becomes unidirectional. According to the second law of thermodynamics energy dissipates while entropy (disorder) increases. In our consciousness of the everyday succession of events we also experience a unidirectional arrow of time. We cannot unsee, unhear, unknow, etc. our experience of the processes of perception and cognition. So, we might ask, which time is real time? Conceivably there is something deficient in our idea of time.
We experience the forward movement of consciousness/freedom in the form of an implied knowledge of our environment (what follows is my understanding of what is deficient in our notion of time). In itself, this “passage of time” does not produce a great deal of knowledge, but because we bring the logical relationships implicit in the structure of b~b~bb (being what is not while not being what is, i.e., the logical operators—and, or, and implies– to bear on the experience of an event), we may form judgments concerning the significance and the probable cause of events. These judgments are determined valid across a continuum which ranges from sensation divorced from theory at one end, to, at the other, sensation reinforced by the most advance and respected scientific theories available. This temporal experience, i.e., judging the significance and cause of an event, is the human experience of “time of mind,” the same temporal experience that confused Saint Augustine (as quoted at the top of this post). Once you recognize the two-sided nature of “time”–physical (b~b) and “time of mind” (~bb) then our experience of time becomes both consistent and coherent. Thanks for the opportunity to post.
