''The dearest freshness deep down things''

Perceiving nature's freshness is a joy. And with that joy is another joy, when you know that men cannot degrade this freshness, -they cannot alter it, cannot destroy it, because it is an incessant physical fact : at every moment, every material thing is a new thing. No one, nothing can rob you of this quality of freshness -no noise, no industry, no pollution, no war. These calamities can only alter your circumstances, your physical or mental health, can only disrupt your perception of nature, but they cannot disrupt the physical phenomenon of incessant newness -and seeing this is a joy. Cities are most of the time awfully noisy and oppressive, but cannot prevent physical things to be incessantly renewed, and (so far) you may sit for a while in a park, or travel, hike, walk, far from the urban built environment and wander in nature, lonely as a cloud, or even live in a country house with blue hydrangeas and a great garden with raspberries, and at every moment breathe a new air and see new leaves, new trees, new stones under a new sun.

These two joys inspired Gerard Manley Hopkins to write one of his poems, God's Grandeur :

The world is charged with the grandeur of God.

It will flame out, like shining from shook foil;

It gathers to a greatness, like the ooze of oil

Crushed. Why do men then now not reck his rod ?

Generations have trod, have trod, have trod ;

And all is seared with trade ; bleared, smeared with toil;

And wears man's smudge, and shares man's smell [...].

And for all this, nature is never spent;

There lives the dearest freshness deep down things [...].

At every moment, you may go outside and feel, all senses awakened, that the world is continuously new, and may say to yourself : everything's fine : nature is never spent, freshness never faded.

And for all this, nature is never spent.
