The same law holds good in the development of mind. It has now reached such an altitude, and it shines with such lustre, that our imagination can hardly find the way down to the morning horizon of its life, and measure its scope and power in the dim twilight of its first hours in time. The simple fact of its first condition would now seem to most men as exaggerated fancies, if given in the simplest forms of truthful statement. With all the mighty faculties to which it has come; with its capacity to count, name, measure and weigh stars that Adam, nor Moses, nor Solomon ever saw; with all the forces of nature it has subdued to the service of man, it cannot tell what simplest facts of the creation had to be ascertained by its first, feeble and confused reasonings. No one of to-day can say how low down in the scale of intelligence the human mind began to exercise its untried faculties; what apposition and deduction of thoughts it required to individualise the commonest objects that met the eye; even to determine that the body it animated was not an immovable part of the earth itself; to obtain fixed notions of distance, of color, light, and heat; to learn the properties and uses of plants, herbs, and fruits; even to see the sun sink out of sight with the sure faith that it would rise again. It was gifted with no instinct, to decide these questions instantly and mechanically. They had all to pass through the varied processes of reason. The first bird that sang in Eden, built its first nest as perfectly as its last. But, thought by thought, the first human mind worked out conclusions which the dullest beast or bird reached instantly without reason. What wonderful co-working of internal and external influences was provided to keep thought in sleepless action; to open, one by one, the myriad petals of the mind! Nature, with all its shifting sceneries, filled every new scope of vision with objects that hourly set thought at play in a new line of reflection. Then, out of man's physical being came a thousand still small voices daily, whispering, Think! think! The first-born necessities, few and simple, cried, "_Think_! for we want bread, we want drink, we want shelter and raiment against the cold." The finer senses cried continually, "Give! give thought to this, to that." The Eye, the Ear, the Palate and every other organ that could receive and diffuse delight, worked the mental faculties by day and night, up to the last sunset of the antediluvian world; and all the intellectual result of this working Noah took with him into the ark, and gave to his sons to hand over to succeeding ages. Flowers that Eve stuck in the hair of the infant Abel are just now opening the last casket of their beauty to the favored children of our time. This, in itself, is a marvellous instance of the law we are noticing. But what is this to the processes of thought and observation through which the mind of man has reached its present
