“Animals make noises with expressive and signalling functions, but to these two purposes, virtually always present in human speech, man has added at least two more, the descriptive and the argumentative functions (though the most sophisticated forms of animal communication, like the dance of the bees, already include some very rudimentary descriptive messages). Language made possible, among so many other things, the formulation of descriptions of the world, and thus made understanding possible. It gave rise to the concepts of truth and falsity. In short it made the development of reason possible - or rather was itself a part of the development of reason - and thus marked the emergence of man from the animal kingdom.”

“The traditional view of scientific method had the following stages in the following order, each giving rise to the next: I, observation and experiment; 2, inductive generalization; 3, hypothesis; 4, attempted verification of hypothesis; 5· proof or disproof; 6, knowledge. Popper replaced this with: I, problem (usually rebuff to existing theory or expectation); 2, proposed solution, in other words a new theory; 3· deduction of testable propositions from the new theory; 4, tests, i.e. attempted refutations by, among other things (but only among other things), observation and experiment; 5· preference established between competing theories.”
