“Trying to understand the brain's abilities leads to philosophical difliculties. Penrose (1994) argues that the task is sterile and that science, including neural networks, has not yet advanced to the stage where it can explain conscious thought. At the other extreme there are philosophers such as Fodor (1975) who believed that thought has language-like properties and can be analysed in the same logical way as one can anlayse the structure of language.”

Context: But if thought corrupts language, language can also corrupt thought. A bad usage can spread by tradition and imitation even among people who should and do know better.
Context: All issues are political issues, and politics itself is a mass of lies, evasions, folly, hatred, and schizophrenia. When the general atmosphere is bad, language must suffer. I should expect to find — this is a guess which I have not sufficient knowledge to verify — that the German, Russian and Italian languages have all deteriorated in the last ten or fifteen years, as a result of dictatorship.
But if thought corrupts language, language can also corrupt thought. A bad usage can spread by tradition and imitation even among people who should and do know better.

Context: Metaphysics has a long and distinguished history, and it is consequently unlikely that there are any new truths to be discovered in descriptive metaphysics. But this does not mean that the task of descriptive metaphysics has been, or can be, done once for all. It has constantly to be done over again. If there are no new truths to be discovered, there are old truths to be rediscovered. For though the central subject-matter of descriptive metaphysics does not change, the critical and analytical idiom of philosophy changes constantly. Permanent relationships are described in an impermanent idiom, which reflects both the age’s climate of thought and the individual philosopher’s personal style of thinking. No philosopher understands his predecessors until he has re-thought their thought in his own contemporary terms; and it is characteristic of the very greatest philosophers, like Kant and Aristotle, that they, more than any others, repay this effort of re-thinking
