Professional career

Subhash Kak completed his Ph.D. at the Indian Institute of Technology, Delhi in 1970. He taught there and also at Imperial College London, Bell Laboratories, and the Tata Institute of Fundamental Research (TIFR). He joined the LSU faculty in 1979.

His claims concerning the astronomy of the Vedic period in his book The Astronomical Code of the Rgveda (1994) challenged academic views related to the Aryan invasion theory and the nature of early Indian science. The co-authored In Search of the Cradle of Civilization (1995) led to an intensification of the polemics on the origins of Indian culture and supported the Out of India theory.

Philosophy of science and reality

Kak is a founder of a biannual conference on science and consciousness that has been held in North Carolina beginning in the 1990s. Kak maintains that a fundamental subject-object dichotomy makes it possible for science only to deal with objects and not with the perceiving subject and, therefore, it is impossible to create a formal science of consciousness. Since the mind can make models of the outer reality, which, at its deepest level, is quantum mechanical, he argues that the mind must have a quantum mechanical basis. But his view of how the brain works is different from other quantum approaches to it. He sees the brain as a machine that reduces the infinite possibilities of a quantum-like universal consciousness, which is a consequence of the recursive nature of reality. The mind can only operate sequentially while reality is simultaneous across countless dimensions, suggesting that such a reduction from a universal consciousness may explain the amazing feats of savants and creative people. Consciousness is a quality of the mind generally regarded to comprise qualities such as subjectivity, self-awareness, sentience, sapience, and the ability to perceive the relationship between oneself and ones environment. ...

His ideas on mind and consciousness are scattered in a variety of writings. The most accessible sources for his philosophy of recursionism are his books The Gods Within, The Architecture of Knowledge, the cryptic The Prajna Sutra, and his numerous journal and encyclopedia articles. Recursionism means a variety of things to different people. ...
