Men at that period subsisted upon the spontaneous productions of the ground: a state of simplicity to which they did not long adhere, but applied themselves to the invention of various arts, indicated by the tree of knowledge of good and evil, that is the knowledge of those things which may be either used properly, or abused; which Philo calls a middle kind of wisdom. In this view, Solomon says, God hath created men upright, that is, in simplicity, but they have sought out many inventions, or, in the language of Philo, they have inclined to subtilty. In the sixth oration of Dion Prusaeensis it is said, "the descendants have degenerated from the innocence of primitive times, contriving many subtile inventions no way conducive to the good of life; and using their strength not to promote justice, but to gratify their appetites." Agriculture and pasturage seem to have been the most ancient pursuits, which characterized the first brothers. Some distribution of things would necessarily follow these different states; and we are informed by holy writ, that the rivalry thus created ended in murder. At length men increasing in wickedness by their evil communications with each other, the race of Giants, that is of strong and violent men appeared, whom the Greeks denominate by a title, signifying those who make their own hands and strength the measure of justice. The world in progress of time being cleared of this race by the deluge, the savage was succeeded by a softer and more sensual way of life, to which the use of wine proved subservient, being followed by all the evil consequences of intoxication. But the greatest breach in the harmony of men was made by ambition, which is considered in some measure, as the offspring of a noble mind. Its first and most eminent effects appeared in the attempt to raise the tower of Babel; the failure of which caused the dispersion of mankind, who took possession of different parts of the earth.
