It is true, however, that Pliny does not seem to have been a man of much scientific training and experience. He said himself that his days were taken up with the performance of public duties, and that consequently his scientific labors were largely carried on in the evening hours.[55] Probably we should regard his book as little more than a compilation, and perhaps no very judicious compilation at that, in view of his maxim that there is no book so bad but that some good may be got from it.[56] Perhaps we may not unjustly picture him to ourselves as collecting his material in a rather haphazard fashion; as not always aware of the latest theories or discoveries; as occasionally citing a fantastic writer instead of a more sober one; or as quoting incorrectly statements which his limited scientific knowledge prevented him from comprehending. Perhaps, too, he derived some of his data directly from popular report and superstition. Certainly to us to-day his work seems a disorderly and indiscriminate conglomeration of fact and legend on all sorts of subjects—disorderly, in that its author does not seem to have made any effort to sift his material, to compare and arrange his facts, even in his own mind; indiscriminate, in that Pliny seems to lack any standard of judgment between the true and the false, and to deem almost nothing too improbable, silly or indelicate to be mentioned. Ought we to consider such a work as truly representative of the beliefs of preceding centuries, or as an example of the best educated thought and science of its author’s own age? This is a question which we must consider.
