It is best to revere the powers that make both good and evil, and to remember that the keenest, worldly, practical minds are not the minds that best perceive the great truths and mysteries of existence.

Here is another little bit, reminding us somewhat of Goethe's quatrain, already quoted.
Lives there whom pain hath evermore passed by And sorrow shunned with an averted eye?
Him do thou pity,--him above the rest, Him, of all hapless mortals most unblessed.
That needs no commentary, and it contains a large truth in small space.
Here is a little bit on the subject of the artist's ambition, which is also good.
The thousand painful steps at last are trod, At last the temple's difficult door we win, But perfect on his pedestal, the God Freezes us hopeless when we enter in.
The higher that the artist climbs by effort, the nearer his approach to the loftier truth, the more he understands how little his very best can achieve.

It is the greatest artist, he who veritably enters the presence of God--that most feels his own weakness; the perception of beauty that other men can not see, terrifies him, freezes him motionless, as the poet says.
Out of all of Watson's epigrams I believe these are the best.

The rest with the possible exception of those on the subject of love seem to me altogether failures.

Emerson and various American poets also attempted the quatrain--but Emerson's verse is nearly always bad, even when his thought is sublime.
