"Thinking consists in envisaging, realizing structural features and structural requirements; proceeding in accordance with, and determined by, these requirements; thereby changing the situation in the direction of structural improvements."

“Repetition is useful, but continuous use of mechanical repetition also has harmful effects. It is dangerous because it easily induces habits of sheer mechanized action, blindness, tendencies to perform slavishly instead of thinking, instead of facing a problem freely.”

“The role of past experience is of high importance, but what matters is what one has gained from experience — blind, understood connections, or insight into structural inner relatedness. What matters is how and what one recalls, hoVi he applies what is recalled, whether blindly, in a piece meal way, or in accordance with the situation.”

“What is Gestalt theory and what does it intend? Gestalt theory was the outcome of concrete investigations in psychology, logic, and epistemology. The prevailing situation at the time of its origin may be briefly sketched as follows. We go from the world of everyday events to that of science, and not unnaturally assume that in making this transition we shall gain a deeper and more precise understanding of essentials.”

“It has long seemed obvious — and is, in fact, the characteristic tone of European science — that “science” means breaking up complexes into their component elements. Isolate the elements, discover their laws, then reassemble them, and the problem is solved. All wholes are reduced to pieces and piecewise relations between pieces.”
