A religious mind is free of all authority. And it is extremely difficult to be free from authority not only the authority imposed by another but also the authority of the experience that one has gathered, which is of the past, which is tradition.
And the religious mind has no beliefs; it has no dogmas; it moves from fact to fact, and therefore the religious mind is the scientific mind.
But the scientific mind is not the religious mind. The religious mind includes the scientific mind, but the mind that is trained in the knowledge of science is not a religious mind.
A religious mind is concerned with the totality not with a particular function, but with the total functioning of human existence.
The brain is concerned with a particular function; it specialises. It functions in specialisation as a scientist, a doctor, an engineer, a musician, an artist, a writer. It is these specialised, narrowed-down techniques that create division, not only inwardly but outwardly.
The scientist is probably regarded as the most important man required by society just now, as is the doctor. So function becomes all-important; and with it goes status, status being prestige.
So where there is specialisation there must be contradiction and a narrowing-down, and that is the function of the brain.
