Higher than the question of our duration is the question of our deserving. Immortality will come to such as are fit for it, and he would be a great soul in future must be a great soul now.
The seat of the soul and the control of voluntary movement - in fact, of nervous functions in general, - are to be sought in the heart. The brain is an organ of minor importance.
Nothing is more stimulating and more salutary to (or for) the inner (or inward) development than the exemple of men devoted to the good. It is in the company of men pursuing a same ideal that the still weavering (or unsteady) soul can set oneself ("se fixer", Fr) and stick to (or attach to) everything that is noble and generous.
We must see that consciousness is neither an isolated soul nor the mere function of a single nervous system, but of that totality of interrelated stars and galaxies which makes a nervous system possible.
