Famous quotes containing the words ideal, observer and/or analysis:
“One who does not know how to discover the pathway to his ideal lives more frivolously and impudently than the man without an ideal.”
—Friedrich Nietzsche (1844–1900)
“The possibility of interpretation lies in the identity of the observer with the observed. Each material thing has its celestial side; has its translation, through humanity, into the spiritual and necessary sphere, where it plays a part as indestructible as any other.”
—Ralph Waldo Emerson (1803–1882)
“Whatever else American thinkers do, they psychologize, often brilliantly. The trouble is that psychology only takes us so far. The new interest in families has its merits, but it will have done us all a disservice if it turns us away from public issues to private matters. A vision of things that has no room for the inner life is bankrupt, but a psychology without social analysis or politics is both powerless and very lonely.”
—Joseph Featherstone (20th century)
