Famous quotes containing the words tentatively and/or activity:
“If I had not come to America, where I felt free to formulate tentatively insights at which I had empathically arrived, I would have accomplished very little. I would never have begun to publish, to teach, to undertake research. Because if one does not find an assenting echo to ones ideas, if one is passed over, as I was in Vienna, then one cannot create. To create, after all, is to believe that what one says will count.”
—Margaret S. Mahler (18971985)
“The Good of man is the active exercise of his souls faculties in conformity with excellence or virtue.... Moreover this activity must occupy a complete lifetime; for one swallow does not make spring, nor does one fine day; and similarly one day or a brief period of happiness does not make a man supremely blessed and happy.”
—Aristotle (384322 B.C.)
