Nevertheless, the word ideal has been so long and universally accepted in this sense, that I think it better to continue the use of it, so only that the reader will be careful to observe the distinction in the sense, according to the subject matter under discussion. At present then, using it as expressive of the noble generic form which indicates the full perfection of the creature in all its functions, I wish to examine how far this perception exists or may exist in nature, and if not in nature, how it is by us discoverable or imaginable.

Now it is better, when we wish to arrive at truth, always to take familiar instances, wherein the mind is not likely to be biassed by any [§ 5. Of Ideal form. First, in the lower animals.]elevated associations or favorite theories. Let us ask therefore, first, what kind of ideal form may be attributed to a limpet or an oyster, that is to say, whether all oysters do or do not come up to the entire notion or idea of an oyster. I apprehend that, although in respect of size, age, and kind of feeding, there may be some difference between them, yet of those which are of full size and healthy condition there will be found many which fulfil the conditions of an oyster in every respect, and that so perfectly, that we could not, by combining the features of two or more together, produce a more perfect oyster than any that we see. I suppose also, that, out of a number of healthy fish, birds, or beasts of the same species, it would not be easy to select an individual as superior to all the rest; neither by comparing two or more of the nobler examples together, to arrive at the conception of a form superior to that of either; but that, though the accidents of more abundant food or more fitting habitation may induce among them some varieties of size, strength, and color, yet the entire generic form would be presented by many, neither would any art be able to add to or diminish from it.

It is, therefore, hardly right to use the word ideal of the generic forms of these creatures, of which we see actual examples; but if we are [§ 6. In what consistent.]to use it, then be it distinctly understood that their ideality consists in the full development of all the powers and properties of the creature as such, and is inconsistent with accidental or imperfect developments, and even with great variation from average size, the ideal size being neither gigantic nor diminutive, but the utmost grandeur and entireness of proportion at a certain point above the mean size; for as more individuals always fall short of generic size than rise above it, the generic is above the average or mean size. And this perfection of the creature invariably involves the utmost possible degree of all those properties of beauty, both typical and vital, which it is appointed to possess.

Let us next observe the conditions of ideality in vegetables. Out of a large number of primroses or violets, I apprehend that, although one or [§ 7. Ideal form in vegetables.]two might be larger than all the rest, the greater part would be very sufficient primroses and violets. And that we could, by no study nor combination of violets, conceive of a better violet than many in the bed. And so generally of the blossoms and separate members of all vegetables.

But among the entire forms of the complex vegetables, as of oak-trees, for instance, there exists very large and constant difference, some being what we hold to be fine oaks, as in parks, and places where they are taken care of, and have their own way, and some are but poor and mean oaks, which have had no one to take care of them, but have been obliged to maintain themselves.

That which we have to determine is, whether ideality be predicable of the fine oaks only, or whether the poor and mean oaks also may be considered as ideal, that is, coming up to the conditions of oak, and the general notion of oak.

Now there is this difference between the positions held in creation by animals and plants, and thence in the dispositions with which we regard [§ 8. The difference of position between plants and animals.]them; that the animals, being for the most part locomotive, are capable both of living where they choose, and of obtaining what food they want, and of fulfilling all the conditions necessary to their health and perfection. For which reason they are answerable for such health and perfection, and we should be displeased and hurt if we did not find it in one individual as well as another.

But the case is evidently different with plants. They are intended fixedly to occupy many places comparatively unfit for them, and to fill [§ 9. Admits of variety in the ideal of the former.]up all the spaces where greenness, and coolness, and ornament, and oxygen are wanted, and that with very little reference to their comfort or convenience. Now it would be hard upon the plant if, after being tied to a particular spot, where it is indeed much wanted, and is a great blessing, but where it has enough to do to live, whence it cannot move to obtain what it wants or likes, but must stretch its unfortunate arms here and there for bare breath and light, and split its way among rocks, and grope for sustenance in unkindly soil; it would be hard upon the plant, I say, if under all these disadvantages, it were made answerable for its appearance, and found fault with because it was not a fine plant of the kind. And so we find it ordained that in order that no unkind comparisons may be drawn between one and another, there are not appointed to plants the fixed number, position, and proportion of members which are ordained in animals, (and any variation from which in these is unpardonable,) but a continually varying number and position, even among the more freely growing examples, admitting therefore all kinds of license to those which have enemies to contend with, and that without in any way detracting from their dignity and perfection.

So then there is in trees no perfect form which can be fixed upon or reasoned out as ideal; but that is always an ideal oak which, however poverty-stricken, or hunger-pinched, or tempest-tortured, is yet seen to have done, under its appointed circumstances, all that could be expected of oak.

The ideal, therefore, of the park oak is that to which I alluded in the conclusion of the former part of this work, full size, united terminal curve, equal and symmetrical range of branches on each side. The ideal of the mountain oak may be anything, twisting, and leaning, and shattered, and rock-encumbered, so only that amidst all its misfortunes, it maintain the dignity of oak; and, indeed, I look upon this kind of tree as more ideal than the other, in so far as by its efforts and struggles, more of its nature, enduring power, patience in waiting for, and ingenuity in obtaining what it wants, is brought out, and so more of the essence of oak exhibited, than under more fortunate conditions.
