With the birth of mental-consciousness comes the knowledge that there is a mind in others. Man is able to speculate and reason about the mental states of other men, because he recognizes these states within himself. As man advances in the Mental Consciousness he begins to develop a constantly increasing degree and grade of Intellect, and accordingly he attaches the greatest importance to that part of his nature. Some men worship Intellect as a God, ignoring its limitations which other thinkers have pointed out. Such people are apt to reason that because the human intellect (in its present state of development) reports that such a thing _must_ be, or _cannot_ possibly be, that the matter is forever settled. They ignore the fact that it is possible that Man's Intellect, in its present state of unfoldment, may be able to take cognizance of only a very small part of the Universal Fact, and that there may be regions upon regions of Reality and Fact of which he cannot even dream, so far are they removed from his experience. The unfoldment of a new sense would open out a new world and might bring to light facts that would completely revolutionize our entire world of conceptions by reason of the new information it would give us. But, nevertheless, from this Mental Consciousness has come the wonderful work of Intellect, as shown in the achievements of Man up to this time, and while we must recognize its limitations, we gladly join in singing its praises. Reason is the tool with which Man is digging into the mine of Facts, bringing to light new treasures every day. This stage of Mental Consciousness is bringing to Man knowledge of himself--knowledge of the Universe--that is well worth the price he pays for it. For Man _does_ pay a price for entrance into this stage--and he pays an increasing price as he advances in its territory, for the higher he advances the more keenly he feels and suffers, as well as enjoys. Capacity for pain is the price Man pays for Attainment, up to a certain stage. His pain passes from the Physical to the Mental consciousness, and he becomes aware of problems that he never dreamt existed, and the lack of an intelligent answer produces mental suffering. And the mental suffering that comes to him from unsatisfied longings, disappointment, the pain of others whom he loves, etc., is far worse than any physical suffering.
