And it is not that we are to suppose that animals are ignorant of these means of defence, for we have already had occasion to point out[4] the preparations which they make against the attacks of the serpent, and the methods they devise for effecting a cure when wounded by it; and yet, among them all, there is not one that fights by the aid of the poison that belongs to another, with the sole exception of man. Let us then candidly confess our guilt, we who are not contented even with the poisons as Nature has produced them; for by far the greater portion of them, in fact, are artificially prepared by the human hand! And then besides, is it not the fact, that there are many men, the very existence of whom is a baneful poison, as it were? Like that of the serpent, they dart their livid tongue, and the venom of their disposition corrodes every object upon which it concentrates itself. Ever vilifying and maligning, like the ill-omened birds of the night, they disturb the repose of that darkness which is so peculiarly their own, and break in upon the quiet of the night even, by their moans and wailings, the only sounds they are ever heard to emit. Like animals of inauspicious presage, they only cross our path to prevent us from employing our energies or becoming useful to our fellow-men; and the only enjoyment that is sought by their abominable aspirations is centred in their universal hatred of mankind. Still, however, even in this respect Nature has asserted her majestic sway; for how much more numerous[5] are the good and estimable characters which she has produced! just in the same proportion that we find her giving birth to productions which are at once both salutary and nutritious to man. It is in our high esteem for men such as these, and the commendations they bestow, that we shall be content to leave the others, like so many brakes and brambles, to the devouring flames of their own bad passions, and to persist in promoting the welfare of the human race; and this, with all the more energy and perseverance, from the circumstance that it has been our object throughout, rather to produce a work of lasting utility than to ensure ourselves a widely-spread renown. We have only to speak, it is true, of the fields and of rustic operations; but still, it is upon these that the enjoyment of life so materially depends, and that the ancients conferred the very highest rank in their honours and commendations.
