In the decades that followed, in the midst of the revolution occasioned by the emergence of Einstein’s relativity and quantum physics, a growing number of authors claimed to discover striking “par- allels” between Advaita Ved¯anta and modern physics. Such claims of convergence have continued to the present day, especially in relation to quantum physics. In this dissertation, an attempt is made to critically examine such claims by engaging a de- tailed comparative analysis of two concepts: ¯ak¯a´sa in Advaita Ved¯anta and vacuum in quantum physics. What is examined is the claim that both concepts would refer to the same reality — an enduring, subtle and all-pervading physical substratum out of which the constituents of the world come into existence and to which they ulti- mately return. Based on this study, the dissertation argues that comparisons relying on conceptual affinities alone generally fall short of establishing a productive dia- logue between Advaita Ved¯anta and modern physics. Another approach is to bring into focus the epistemological limits respectively encountered by these systems when attempting to define the content of “reality-in-itself” or “ultimate reality.” Emphasis is given to epistemology and the problem of reality in Advaita Ved¯anta, and scientific realism and philosophical implications of nonseparability in quantum physics.

Au cours des d´ecennies suiv- antes, suite aux apports scientifiques r´evolutionnaires de la th´eorie de la relativit´e d’Einstein et de la physique quantique, un nombre croissant d’auteurs soutenaient que d’importants “parall`eles” pouvaient ˆetre trac´es entre l’Advaita Ved¯anta et la physique moderne. Encore aujourd’hui, de tels rapprochements sont faits, particuli`erement en relation avec la physique quantique. Cette th`ese examine de mani`ere critique ces rapprochements `atravers l’´etude comparative d´etaill´ee de deux concepts: le concept d’¯ak¯a´sa dans l’Advaita Ved¯anta et celui de vide en physique quantique. L’´enonc´eex- amin´eest celui selon lequel ces deux concepts pointeraient vers une mˆeme r´ealit´e: un substratum omnipr´esent et subtil duquel ´emergent et auquel retournent ultimement les divers constituants de l’univers. Sur la base de cette ´etude comparative, la th`ese argumente que des comparaisons de nature conceptuelle favorisent rarement la mise en place d’un v´eritable dialogue entre l’Advaita Ved¯anta et la physique moderne. Une autre voie d’approche serait de prendre en consid´eration les limites ´epist´emologiques respectivement rencontr´ees par ces disciplines dans leur approche du “r´eel-en-soi” ou de la “r´ealit´eultime.” Une attention particuli`ere sera port´ee sur l’´epist´emologie et le probl`eme de la nature de la r´ealit´edans l’Advaita Ved¯anta, ainsi que sur le r´ealisme scientifique et les implications philosophiques de la non-s´eparabilit´een physique quan- tique.

Rukmani from Concordia University (Department of Religion), and Prof. Normand Mousseau from University of Montreal (Department of Physics) — for their continuous support in this research. Without the vision and insights of Prof. Rukmani, who was the first to hear about my ideas, this study would not have been possible at all. She has been my first guru in the academic world of Indian philosophy, and was always there to listen and give judicious advices on my research and other areas of life as well. Without her constant guidance and patience (in proofreading my chapters, English and fellowship applications!), things would have been much more difficult for me. Prof. Mousseau has been a real motivating force in the course of this project in challenging me with good and pertinent questions when necessary. His intelligence and energy have impressed me, and his hard work has reminded me of the need to be persistent to accomplish any goal in life. He was always there to meet and talk about my ideas whether scientific, philosophical or academic, and I have greatly appreciated that. Besides my advisors, I would like to thank the rest of my thesis committee, and particularly: Prof. Solange Lefebvre, who introduced me to religious studies by giving me my first job as a research assistant in a Templeton project, and also agreed with my Ph.D. research project at its very beginnings; and Prof.
