All things living show signs of their existence, and it follows that these signs could not of themselves exist if that which they express or to which they testify had no being. A thing which does not exist, can, of course, give no sign of its existence. The manifold signs of the existence of the spirit are for ever before us. The traces of the Spirit of Jesus Christ, the influence of His Divine Teaching, is present with us today, and is everlasting. A non-existent thing, it is agreed, cannot be seen by signs.
Writing is, in itself, a sign of the writer's soul and intelligence.
Thus, man is shown to be the sum of all creation, the superior of all created beings, the goal to which countless ages of existence have progressed. The soul is eternal, immortal. We cannot see it, neither can we touch it'. The animal, be he never so highly developed, cannot imagine the intelligence of man, neither can he realize the nature of his soul. But, again, this does not prove that man is without intellect, or without soul.
