A Journey Into The Brain - Understand the nature of your thoughts

Many of us now take for granted the routine extraction of information about the mind and brain, but it is a fairly recent phenomena. For most of history, the software of the mind was a deep mystery. True, people long suspected that the tissue behind their eyes was somehow responsible for the decisions they made and the emotions they felt. 

Everything we know about the world comes to us through our brain. Yet for each of us our own conscious mental world of thoughts and feelings is isolated and private. Despite several centuries of research on the brain, communication through language or gesture remains the only way we can discover the conscious thoughts and experiences of others.

Mind and body - The Expressions Of Life

Mind and body are parts of the whole of life. And we begin to understand their reciprocal relations in that whole. The life of man is the life of a moving being, and it would not be sufficient for him to develop body alone. All moving beings, however, can foresee and reckon up the direction in which to move; and this fact makes it necessary to postulate that they have mind. This foreseeing the direction of movement is the central principle of the mind.
