As you are aware, no perceptions obtained by the senses are merely sensations impressed on our nervous systems. A peculiar intellectual activity is required to pass from a nervous sensation to the conception of an external object, which the sensation has aroused. The sensations of our nerves of sense are mere symbols indicating certain external objects, and it is usually only after considerable practice that we acquire the power of drawing correct conclusions from our sensations respecting the corresponding objects.

I never turned recreant to intellectual culture, or ceased to consider the power and practice of analysis as an essential condition both of individual and of social improvement. But I thought that it had consequences which required to be corrected, by joining other kinds of cultivation with it. The maintenance of a due balance among the faculties, now seemed to me of primary importance. The cultivation of the feelings became one of the cardinal points in my ethical and philosophical creed.
John Stuart Mill
If we cannot "practice the presence of God," it is something to practice the absence of God, to become increasingly aware of our unawareness till we feel like man who should stand beside a great cataract and hear no noise, or like a man in a story who looks in a mirror and finds no face there, or a man in a dream who stretches his hand to visible objects and gets no sensation of touch. To know that one is dreaming is to no longer be perfectly asleep. Bur for news of the fully waking world you must go to my betters.
C. S. Lewis
The new hero-type favored by Aschenbach, and recurring in his books in a multiplicity of individual variants, had already been remarked upon at an early stage by a shrewd commentator, who had described his conception as that of "an intellectual and boyish manly virtue, that of a youth who clenches his teeth in proud shame and stands calmly on as the swords and spears pass through his body ... the figure of Saint Sebastian is the most perfect symbol if not of art in general, then certainly of the kind of art in question.
Thomas Mann
Depth, in a pictorial, plastic sense, is not created by the arrangement of objects one after another toward a vanishing point, in the sense of the Renaissance perspective, but on the contrary (and in absolute denial of this doctrine) by the creation of forces in the sense of push and pull . Nor is depth created by tonal gradation (another doctrine of the academician which, at its culmination, degraded the use of color to a mere function of expressing dark and light).
Hans Hofmann
Faculty Psychology is getting to be respectable again after centuries of hanging around with phrenologists and other dubious types. By faculty psychology I mean, roughly, the view that many fundamentally different kinds of psychological mechanisms must be postulated in order to explain the facts of mental life. Faculty psychology takes seriously the apparent heterogeneity of the mental and is impressed by such prima facie differences as between, say, sensation and perception, volition and cognition, learning and remembering, or language and thought.
