Extensionalism makes it possible to study logic independently of any theory of meaning. Frege’s logic was not fully extensional, however: he developed a theory of meaning in order to have classes uniquely determined. That theory is also flexible enough to allow statements of identity to be at times analytic, at times not. He rejected the traditional empiricist epistemology as an obstacle since it is psychologistic – even though he could not replace it. (A few years after Frege died Popper proposed the first non-psychologistic theory of science.)

The hermeneutic literature in Wittgenstein will benefit from following the rules of hermeneutics more closely. This will suit the view of him as a moralist. And then, although he thought he was great and would have been disappointed to learn that he was not, if this option is to be overruled, this should not be taken as self-understood. Even though commentators take for granted that his influence was beneficial, they have to discuss it, and to be ready to consider seriously some criticism of his views and of his lifework. On the whole, as far as the concern is with the verdict on Wittgenstein, at present the jury is still out.

Self- Deception in General "A Liberal Decalogue" suggests (Russell, 1967, pp. 60-61) not to envy people who live in a fool's paradise: It is a place only for fools. This saying invites detailed commentary. A fool's paradise is not a place, but a state o f mind; it is a system of opinions, of assessments of situations, that calms one down, that reassures one into the opinion that all is well, even when all is far from well. Fools may be ignorant of the severity of their situations, perhaps because being well informed tends to get them into a panic. This happens regularly, and there is little that can be done about it, except that the wise would still prefer to be well informed so as to try to cope with the panic more constructively. They would not easily fa ll for the reassuring hypothesis, preferring to examine any reasonable alternative hypothesis about any risk that might invite action - - so that if the hypothesis is corroborated they can try to mobilize some appropriate action.

Summary and conclusions As a new field, cognitivism began with the total rejection of the old, traditional views of language acquisition and of learning -- individual and collective alike. Chomsky was one of the pioneers in this respect, yet he clouds issues by excessive claim s for his originality and by not allowing the beginner in the art of the acquisition of language the use of learning by making hypotheses and testing them, though he acknowledges that researchers, himself included, do use this method.

Basic research or fundamental research is distinct from both pure and applied research, in that it is pure research with expected useful results. The existence of basic or fundamental research is problematic, at least for both inductivists and instrumentalists, but also for Popper. Assuming scientific research to be the search for explanatory conjectures and for refutations, and assuming technology to be the search of conjectures and some corroborations, we can easily place basic or fundamental research between science and technology as a part of their overlap. As a bonus, the present view of basic or fundamental research as an overlap explains the specific hardship basic research workers encounter.
