We need science. We need empirical evidence. We can't just use mathematical reasoning to deduce the nature of the world.
In enabling mechanism to combine together general symbols in successions of unlimited variety and extent, a uniting link is established between the operations of matter and the abstract mental processes of the most abstract branch of mathematical science.
I have written occasionally on links between my scientific work and political thinking, but not much, because the links seem to me abstract and speculative.
My final remark to young women and men going into experimental science is that they should pay little attention to the speculative physics ideas of my generation. After all, if my generation has any really good speculative ideas, we will be carrying these ideas out ourselves.
A system is empirical or scientific only if it is capable of being tested by experience. These considerations suggest that not the verifiability but the falsifiability of a system is to be taken as a criterion of demarcation... It must be possible for an empirical or scientific system to be refuted by experience.
There is no reason why an extraphysical general principle is necessarily to be avoided, since such principles could conceivably serve as useful working hypotheses. For the history of scientific research is full of examples in which it was very fruitful indeed to assume that certain objects or elements might be real, long before any procedures were known which would permit them to be observed directly.
Taken over the centuries, scientific ideas have exerted a force on our civilization fully as great as the more tangible practical applications of scientific research.
The technological overflow from scientific research has brought scientific research this bad name about carrying an irresponsibility and an alienation from God - because scientific research has led to things like the atom bomb, it's led to problems with depletion of ozone in the Earth's atmosphere, or at least it's revealed those problems.
What's nice about experiments is that they are much more closely tied to what theorists think about the world than normal empirical research. You can design your experiment to exactly ask the question you want to ask. This is not true about normal empirical research.
The new advocates of ID [Intelligent Design] ask that their ideas be judged by scientific, not religious, criteria. OK, let's see how well ID stacks up as a scientific alternative to Darwinism. To gauge how well ID is doing as a platform for scientific research, I logged into the best database of the biological literature. A search for keyword ''evolution'' yielded 24,000 hits in the last decade. A search for ''intelligent design'' yielded not a single piece of research. Evolution by natural selection remains the basis of every successful biological research program.
Both induction and deduction, reasoning from the particular and the general, and back again from the universal to the specific, form the essence to scientific thinking.
A man demonstrates his rationality, not by a commitment to fixed ideas, stereotyped procedures, or immutable concepts, but by the manner in which, and the occasions on which, he changes those ideas, procedures, and concepts.
Speculative Philosophy is the endeavour to frame a coherent, logical, necessary system of general ideas in terms of which every element of our experience can be interpreted. By this notion of 'interpretation' I mean that everything of which we are conscious, as enjoyed, perceived, willed, or thought, shall have the character of a particular instance of the general scheme.
A hypothesis is empirical or scientific only if it can be tested by experience. A hypothesis or theory which cannot be, at least in principle, falsified by empirical observations and experiments does not belong to the realm of science.
I write speculative fiction, and in my view, speculative fiction is really just a very intense version of the work of literature in general.
A healthy economics has got to have both conceptual, theoretical research and applied, empirical research.
