    Reasoning and Semantic Computation

    Since the advent of computers, it has been widely believed that the human mind is just like a computer. I have previously described why this is a false analogy due to two problems: (1) the problem of meaning, and (2) the problem of choice. I have also discussed the problem of meaning in computing theory in the book Gödel’s Mistake. However, all these critiques are inadequate without an understanding of how nature itself computes. For example, if nature is governed by some natural laws, then these laws have to be computed on some machine to obtain a prediction. How is nature computing these predictions? Even otherwise, living beings are constantly…

    What is the Power of Kundalini?

    In an earlier post, I discussed how the Sāńkhya notion of manifest and unmanifest matter addresses some fundamental problems related to perception and realism. In a later post, I discussed how the unmanifest becomes manifest through several stages—para, pasyanti, madhyama and vaikhari. In a subsequent post, we talked about how the agency to cause this manifestation is prāna, which acts as the “force” of nature, under the control of free will, time, karma, and God. This description leads to a natural doubt: is prāna an objective entity by itself, or is it simply a combined effect of other entities (soul’s choice, time, karma and God)? This post discusses how prāna…

    What is Prāna?

    Sāńkhya divides matter into manas (mind), prāna (life force), and vāk. In the previous post, we discussed the nature of vāk and manas as the relation between word and meaning, or between matter and mind. This post elaborates on the third aspect of matter called prāna. The post discusses the role prāna plays in the motion of material objects, in the creation of bodies, and in the transmigration of the soul. The topic is fairly complex, so reader patience is essential to get through to the end. I will begin with a discussion of the problems of motion in mathematics and physics, because grasping these problems is essential to laying…
