Norman Christopher Vallejo writes: How can a time-dependent equation show change? The answer is…it cannot. Change only appears to occur macroscopically across the instances time dependent equation produces but microscopically, it actually occurs between them. It really is a simple matter of understanding that no matter of effort on Earth will ever be able to provide a physical representation of change. It is impossible.
I believe Henri Bergson has made a similar point in “Creative Evolution,” and this is related to the Trinitarian concept of the synthesis of sending and receiving over a duration.
