Permissible Quotes (9 quotes)
[On the use of scopolamine in criminology], If it is permissible for a state to take life, liberty and property because of crime, it can be made legal to obtain information from a suspected criminal by the use of a drug. If the use of bloodhounds is legal, the use of scopolamine can be made legal.
Creative imagination is likely to find corroborating novel evidence even for the most 'absurd' programme, if the search has sufficient drive. This look-out for new confirming evidence is perfectly permissible. Scientists dream up phantasies and then pursue a highly selective hunt for new facts which fit these phantasies. This process may be described as “science creating its own universe” (as long as one remembers that “creating” here is used in a provocative-idiosyncratic sense). A brilliant school of scholars (backed by a rich society to finance a few well-planned tests) might succeed in pushing any fantastic programme ahead, or alternatively, if so inclined, in overthrowing any arbitrarily chosen pillar of “established knowledge”.
I would beg the wise and learned fathers (of the church) to consider with all diligence the difference which exists between matters of mere opinion and matters of demonstration. ... [I]t is not in the power of professors of the demonstrative sciences to alter their opinions at will, so as to be now of one way of thinking and now of another. ... [D]emonstrated conclusions about things in nature of the heavens, do not admit of being altered with the same ease as opinions to what is permissible or not, under a contract, mortgage, or bill of exchange.
It is one of the signs of the times that modern chemists hold themselves bound and consider themselves in a position to give an explanation for everything, and when their knowledge fails them to make sure of supernatural explanations. Such a treatment of scientific subjects, not many degrees removed from a belief in witches and spirit-rapping, even Wislicenus considers permissible.
It is the responsibility of scientists never to suppress knowledge, no matter how awkward that knowledge is, no matter how it may bother those in power; we are not smart enough to decide which pieces of knowledge are permissible, and which are not. …
Knowledge is a matter of science, and no dishonesty or conceit whatsoever is permissible. What is required is definitely the reverse—honesty and modesty.
The great mathematician fully, almost ruthlessly, exploits the domain of permissible reasoning and skirts the impermissible. … [I]t is hard to believe that our reasoning power was brought, by Darwin’s process of natural selection, to the perfection which it seems to possess.
The ideal chemist of the future will be an investigator, one who dares to think and work with an independent freedom not permissible heretofore, unfolding before our very eyes a veritable mystic maze of new and useful products from material almost or quite beneath our feet and now considered of little or no value. This is the work of the creative research chemist, and it is to this group of workers that the whole civilized world must look for its greatest development.
Until now the theory of infinite series in general has been very badly grounded. One applies all the operations to infinite series as if they were finite; but is that permissible? I think not. Where is it demonstrated that one obtains the differential of an infinite series by taking the differential of each term? Nothing is easier than to give instances where this is not so.
