Letter "J" » Jean Piaget Quotes
«Scientific thought, then, is not momentary; it is not a static instance; it is a process.»
«Scientific knowledge is in perpetual evolution; it finds itself changed from one day to the next.»
«I have always detested any departure from reality, an attitude which I relate to my mother's poor mental health.»
«Logical positivists have never taken psychology into account in their epistemology, but they affirm that logical beings and mathematical beings are nothing but linguistic structures.»
«To express the same idea in still another way, I think that human knowledge is essentially active.»
«Accommodation of mental structures to reality implies the existence of assimilatory schemata apart from which any structure would be impossible.»
«This means that no single logic is strong enough to support the total construction of human knowledge.»
«On the one hand, there are individual actions such as throwing, pushing, touching, rubbing. It is these individual actions that give rise most of the time to abstraction from objects.»
«The first type of abstraction from objects I shall refer to as simple abstraction, but the second type I shall call reflective abstraction, using this term in a double sense.»
«The principle goal of education in the schools should be creating men and women who are capable of doing new things, not simply repeating what other generations have done.»
