Hayagrīva: ...Frenchman, and he is known as a positivist. He felt that positivism reconciles the heart and the intellect. He felt that theology dealt solely with the heart or the sentiments and that philosophy dealt solely with the intellect, but positivism reconciled the two. He writes, "Positivism proves more efficient than theology yet at the same time terminates the disunion which has existed so long between the intellect and the heart. It is a fundamental doctrine of positivism, a doctrine of as great political as philosophical importance, that the heart preponderates over the intellect. When it is said that the intellect should be subordinate to the heart, what is meant is that the intellect should devote itself exclusively to the problems which the heart suggests, the ultimate object being to find proper satisfaction for our various wants," meaning material wants, as well as spiritual wants.
Prabhupāda: So we have got from Bhagavad-gītā that the gross understanding are the senses, though the still finer understanding is the mind, and then intellect, and then the soul. The soul is the original, basic principle of activities. So it becomes grosser, grosser, grosser, and when the soul acts on the platform of senses and body, these are gross activities. So our calculation is the gross activities of the body, then the subtle activities of the mind and still more subtle activities of the intellect, and then spiritual platform. So that is also expressed in another way: pratyakṣa, parokṣa, aparokṣa, adhokṣaja, aprākṛta. These are different stages of knowledge. Direct perception, pratyakṣa; then receiving knowledge from others, then..., pratyakṣa par..., aparokṣa, still further Vedic knowledge. Then adhokṣaja, beyond the experience of mind and senses. Then aprākṛta, transcendental, spiritual. These are the different stages of knowledge and different stages of understanding from gross to the subtler forms of life.
