The world can never be more beautiful than now.

May 18.

It is fine clear atmosphere, only the mountains blue.  Shall we have much of this weather after this? There is scarcely a flock of cloud in the sky. The heaven is now broad and open to the earth in these longest days. 

The world can never be more beautiful than now, for, combined with the tender fresh green, you have this remarkable clearness of the air. I doubt if the landscape will be any greener.

H. D. Thoreau, Journal, May 18, 1852

The world can never be more beautiful than now.  See May 1850 ("I still sit on its Cliff in a new spring day, and look over the awakening woods and the river, and hear the new birds sing, with the same delight as ever. It is as sweet a mystery to me as ever, what this world is. . . ."); May 5, 1852 ("Every part of the world is beautiful today.”); May 17, 1852 ("I was surprised, on turning round, to behold the serene and everlasting beauty of the world. “); May 22, 1854 ("How many times I have been surprised thus, on turning about on this very spot, at the fairness of the earth!”) See also September 18, 1860 ("If you are not happy to-day you will hardly be so to-morrow.") and A Book of the Seasons, by Henry Thoreau, The world can never be more beautiful than now.
