Jeans talks of "Universal Mind' and 'Individual Minds'. The Universal Mind, according to him, is the creator and governor of the realm of matter as well as the individual minds. He believes that atoms out of which our individual minds have grown exist as thought in the Universal Mind.
The Jain view does not accept the existence of any such Universal Mind of which the individual minds are units of excrescences. According to the Jain view, all the souls are independent individual entities having real objective existence. Jeans has not given any reason for his belief which is akin to the pantheistic view.
Now, as we have already seen, the Jain view concedes that the sensory knowledge of the phenomena of the universe may not be wholly objective, but it does not conform with Jeans' views in considering the phenomena of the universe as wholly subjective.
According to Jeans, the objective reality of the real essence of substance is beyond our knowledge. He, thus, seems to accept Kant's transcendentalism in which the thing-in-itself is considered to be transcendental. The Jain philosophy also declares that the ultimate essence of substances cannot be comprehended through the sensory knowledge and hence, at least in this respect, Jeans' view is consistent with the Jain view.
