“Aesthetics, ethics, and many good things in humans are contagious.”
“Ethics and aesthetics are one.”
“Examine each question in terms of what is ethically and aesthetically right, as well as what is economically expedient. A thing is right when it tends to perserve the integrity, stability, and beauty of the biotic community. It is wrong when it tends otherwise.”
“In the world there exists no aesthetic plane, not even the aesthetic plane of goodness.”
“It is a fair, even-handed, noble adjustment of things, that while there is infection in disease and sorrow, there is nothing in the world so irresistibly contagious as laughter and good humour.”
“For Peter's smile is a most contagious thing.”
