One of the features of science is that new discoveries and technological developments often pose new ethical dilemmas to human society. Thus, science and ethics are inextricably connected, quite apart from issues relating to professional ethics.

"We are raising a generation of young men who will not look at any scientific project which does not have millions of dollars invested in it .... We are for the first time finding a scientific career well paid and attractive to a large number of our best young go-getters. The trouble is that scientific work of the first quality is seldom done by the go-getters, and that the dilution of the intellectual milieu makes it progressively harder for the individual worker with any ideas to get a hearing ....The degradation of the position of the scientist as an independent worker and thinker to that of a morally irresponsible stooge in a science-factory has proceeded even more rapidly and devastatingly than I had expected." - Norbert Wiener, Bulletin of the Atomic Scientists 4 November 1948, pp. 338-9.

"The ethical standards of scientists must change as the scope of the good and evil caused by science has changed. In the long run ...ethical progress is the only cure for the damage done by scientific progress." - physicist Freeman Dyson, in "Daedalus after 70 years" in Haldane's Daedalus Revisited.
