Hence, in the first ages, when such inventions and conclusions of the human reason as are now trite and common were new and little known, all things abounded with fables, parables, similes, comparisons, and allusions, which were not intended to conceal, but to inform and teach, whilst the minds of men continued rude and unpractised in matters of subtilty and speculation, or even impatient, and in a manner incapable of receiving such things as did not fall directly under and strike the senses. For as hieroglyphics were in use before writing, so were parables in use before arguments. And even to this day, if any man would let new light in upon the human understanding, and conquer prejudice, without raising contests, animosities, opposition, or disturbance, he must still go in the same path, and have recourse to the like method of allegory, metaphor, and allusion.
To conclude, the knowledge of the early ages was either great or happy; great, if they by design made this use of trope and figure; happy, if, whilst they had other views, they afforded matter and occasion to such noble contemplations. Let either be the case, our pains, perhaps, will not be misemployed, whether we illustrate antiquity or things themselves.
The like, indeed, has been attempted by others; but, to speak ingenuously, their great and voluminous labors have almost destroyed the energy, the efficacy, and grace of the thing; whilst, being unskilled in nature, and their learning no more than that of commonplace, they have applied the sense of the parables to certain general and vulgar matters, without reaching to their real purport, genuine interpretation, and full depth. For myself, therefore, I expect to appear new in these common things, because, leaving untouched such as are sufficiently plain and open, I shall drive only at those that are either deep or rich.
