One of the most important motives concerns the doubts raised by the new truths which science was beginning to teach, almost seeming to make in a sense a new heaven and a new earth. The old simple beliefs seemed to the Poet threatened—these misgivings are evil dreams: Nature seems to say:

... A thousand types are gone:
I care for nothing, all shall go.
Thou makest thine appeal to me;
I bring to life, I bring to death;
The spirit does but mean the breath:
I know no more...

Then the Poet breaks out:

And he, shall he,
Man, her last work, who seem’d so fair,
Such splendid purpose in his eyes,
Who roll’d the psalm to wintry skies,
Who built him fanes of fruitless prayer—
Who trusted God was love indeed,
And love Creation’s final law—
Tho’ Nature, red in tooth and claw
With ravine, shriek’d against his creed—
Who loved, who suffer’d countless ills,
Who battled for the True, the Just,
Be blown about the desert dust,
Or seal’d within the iron hills?...
O life as futile, then, as frail!
O for thy voice to soothe and bless!
What hope of answer, or redress?
Behind the veil, behind the veil.

He will not accept the suggestions which seem to empty human life of its deepest meanings. There must be some other solution.

One more quotation of a different kind—the common sad thought, never so beautifully expressed, of the places we have loved when bereft of our daily loving care—then passing into other hands and forgetting us, and becoming at last to others what they have been to us.

It is in these common universal human themes that Tennyson with his exquisite musical touch, and sympathy, and unerring choice of significant detail, reaches the heart of every reader.

Unwatch’d, the garden bough shall sway,
The tender blossom flutter down,
Unloved, that beech will gather brown,
This maple burn itself away:
Unloved, the sunflower, shining fair,
Ray round with flames her disk of seed,
And many a rose-carnation feed
With summer spice the humming air:
Unloved, by many a sandy bar,
The brook shall babble down the plain,
At noon or when the lesser wain
Is twisting round the polar star.

(Omitting a stanza.)

Till from the garden and the wild
A fresh association blow,
And year by year the landscape grow
Familiar to the stranger’s child.
As year by year the labourer tills
His wonted glebe, or lops the glades,
And year by year our memory fades
From all the circle of the hills.
