Famous quotes containing the words perfect and/or equilibrium:
“A perfect personality ... is only possible in a state of society where man is free to choose the mode of work, the conditions of work, and the freedom to work. One to whom the making of a table, the building of a house, or the tilling of the soil, is what the painting is to the artist and the discovery to the scientist,—the result of inspiration, of intense longing, and deep interest in work as a creative force.”
—Emma Goldman (1869–1940)
“When a person hasn’t in him that which is higher and stronger than all external influences, it is enough for him to catch a good cold in order to lose his equilibrium and begin to see an owl in every bird, to hear a dog’s bark in every sound.”
—Anton Pavlovich Chekhov (1860–1904)
