Emerson, then, is one of the few moral reformers whose mission lay in calming men rather than in rousing them, and in the inculcation of serenity rather than in the spread of excitement. Though he had been ardent in protest against the life conventional, as soon as the protest ran off into extravagance, instead of either following or withstanding it with rueful petulancies, he delicately and successfully turned a passing agitation into an enduring revival. The last password given by the dying Antonine to the officer of the watch was _AEquanimitas_. In a brighter, wider, and more living sense than was possible even to the noblest in the middle of the second century, this, too, was the watchword of the Emersonian teaching. Instead of cultivating the tormenting and enfeebling spirit of scruple, instead of multiplying precepts, he bade men not to crush their souls out under the burden of Duty; they are to remember that a wise life is not wholly filled up by commandments to do and to abstain from doing. Hence, we have in Emerson the teaching of a vigorous morality without the formality of dogma and the deadly tedium of didactics. If not laughter, of which only Shakespeare among the immortals has a copious and unfailing spring, there is at least gaiety in every piece, and a cordial injunction to men to find joy in their existence to the full. Happiness is with him an aim that we are at liberty to seek directly and without periphrasis. Provided men do not lose their balance by immersing themselves in their pleasures, they are right, according to Emerson, in pursuing them. But joy is no neighbour to artificial ecstasy. What Emerson counsels the poet, he intended in its own way and degree for all men. The poet's habit of living, he says beautifully, should be set on a key so low that the commonest influences should delight him. 'That spirit which suffices quiet hearts, which seems to come forth to such from every dry knoll of sere grass, from every pine-stump and half-embedded stone on which the dull March sun shines, comes forth to the poor and hungry, and such as are of simple taste. If thou fill thy brain with Boston and New York, with fashion and covetousness, and wilt stimulate thy jaded senses with wine and French coffee, thou shalt find no radiance of wisdom in the lonely waste of the pinewoods' (ii. 328).
