„Economics is the most human of sciences. It is the science of wants and frustrations. It is psychology subject to the abstract, amplifying forces of mathematics.“

„Psychology is the logos of experience. Psychology is the structure of the evidence, and hence psychology is the science of sciences.“

—  Ronald David Laing Scottish psychiatrist and author 1927 - 1989
Context: I cannot experience your experience. You cannot experience my experience. We are both invisible men. All men are invisible to one another. Experience used to be called The Soul. Experience as invisibility of man to man is at the same time more evident than anything. Only experience is evident. Experience is the only evidence. Psychology is the logos of experience. Psychology is the structure of the evidence, and hence psychology is the science of sciences. Ch. 1 : Experience as evidence

„The branches of mathematics are as various as the sciences to which they belong, and each subject of physical enquiry has its appropriate mathematics.“

—  Benjamin Peirce American mathematician 1809 - 1880
Context: The branches of mathematics are as various as the sciences to which they belong, and each subject of physical enquiry has its appropriate mathematics. In every form of material manifestation, there is a corresponding form of human thought, so that the human mind is as wide in its range of thought as the physical universe in which it thinks. § 2.

„There is a noticeable general difference between the sciences and mathematics on the one hand, and the humanities and social sciences on the other.“

—  Noam Chomsky american linguist, philosopher and activist 1928
Context: There is a noticeable general difference between the sciences and mathematics on the one hand, and the humanities and social sciences on the other. It's a first approximation, but one that is real. In the former, the factors of integrity tend to dominate more over the factors of ideology. It's not that scientists are more honest people. It's just that nature is a harsh taskmaster. You can lie or distort the story of the French Revolution as long as you like, and nothing will happen. Propose a false theory in chemistry, and it'll be refuted tomorrow.

„Psychology is a very unsatisfactory science.“

—  Kurt Koffka German psychologist 1886 - 1941
Context: Psychology is a very unsatisfactory science. Comparing the vast body of systematised and recognised facts in physics with those in psychology one will doubt the advisability of teaching the latter to anybody who does not intend to become a professional psychologist, one might even doubt the advisability of training professional psychologists. But when one considers the potential contribution which psychology can make to our understanding of the universe, one's attitude may be changed. Science becomes easily divorced from life. The mathematician needs an escape from the thin air of his abstractions, beautiful as they are; the physicist wants to revel in sounds that are soft, mellow, and melodious, that seem to reveal mysteries which are hidden under the curtain of waves and atoms and mathematical equations; and even the biologist likes to enjoy the antics of his dog on Sundays unhampered by his weekday conviction that in reality they - are but chains of machine-like reflexes p. 22.
