And as there is the sense of this profounder life in nature, this deeper, mysterious unity, back of all the varied shift and change, so there is the passionate desire to be at one with that unity, to lose one’s miserable, insignificant, turbulent, tormenting I in that vast, illimitable, measureless All. There is the thirst of Shelley’s ‘Adonais’: ‘That sustaining love, Which, through the web of being blindly wove By man and beast and earth and air and sea, Burns bright or dim, as each are mirrors of The fire for which all thirst.’ There is Byron’s cry: ‘I live not in myself, but I become Portion of that about me, and to me High mountains are a feeling.’[204] And with the realization that the longing cannot be satisfied, that we are forever imprisoned within the insuperable barriers of this petty I, from which there is no escape, comes a bitter revolt of despair, or a profound melancholy of questioning. It is Obermann, with his, ‘There, in the peace of night, I questioned my uncertain destiny, and this inconceivable universe, which, containing everything yet does not contain my desires.’[205] Or, as an American contemporary has expressed the deep suggestion of the earnest stars: ‘O Lyra, I have gazed at you, until I could not tell your brightness from my own eyes. I have gazed at you till my soul left my body, and circled with you through the stars; but there is something which I am and you are not, something which will not let me rest.... ‘Infinite Intelligence! Infinite Beauty! Either make me what thou art, take me to thyself, or free me from this passion which I cannot gratify and cannot destroy. Make me as other men are, toilers and forgetters, seeking yesterday in to-day, and to-day in to-morrow, and illusion always; or fulfill for me the hope which the waters whisper, which I can feel throbbing forever in the heart of thy world.’ Of all this in Darwin nothing whatever, nothing, nothing. It may indeed be said that with nature, as with other things, many people have feelings and experiences that they do not express or try to express. But persons who cherish such experiences with the natural world usually have a more constant regard and interest for the expression of them in others than Darwin had. Any such melancholy or passionate longing as is suggested above one would of course not expect in him. There was no natural melancholy in his temperament. He was depressed and discouraged when things went badly, yet in the main his disposition was even and serene. But his enjoyment of natural scenes and objects, which is indisputable and proved by his own testimony and that of others, would seem to have been generally of a rather superficial character, and certainly not to have partaken of the nature of passion. How far, far different is his touch from that of Lucretius, for example.
