Reflective abstraction, however, is based not on individual actions but on coordinated actions.
The goal of education is not to increase the amount of knowledge but to create the possibilities for a child to invent and discover, to create men who are capable of doing new things.
The child often sees only what he already knows. He projects the whole of his verbal thought into things. He sees mountains as built by men, rivers as dug out with spades, the sun and moon as following us on our walks.
Scientific thought, then, is not momentary; it is not a static instance; it is a process.
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.
Logic and mathematics are nothing but specialised linguistic structures.
This means that no single logic is strong enough to support the total construction of human knowledge.
