All things change, nothing is extinguished. There is nothing in the whole world which is permanent. Everything flows onward; all things are brought into being with a changing nature; the ages themselves glide by in constant movement.
Science is out of the reach of morals, for her eyes are fixed upon eternal truths. Art is out of the reach of morals, for her eyes are fixed upon things beautiful and immortal and ever-changing.
Nothing that is can pause or stay; / The moon will wax, the moon will wane, / The mist and cloud will turn to rain, / The rain to mist and cloud again, / Tomorrow be today.
First follow Nature, and your judgment frame
By her just standard, which is still the same:
Unerring nature, still divinely bright,
One clear, unchanged, and universal light,
Life, force, and beauty must to all impart,
At once the source, and end, and test of art.
Whenever our life is stirred by truth, it expresses energy and comes to be filled, as it were, with a creative ardor. This consciousness of the creative urge is evidence of the force of truth on our mind.
