Andreas Ramos finds it very surprising that we are still honouring Goodman's thoughts on 'grue'. But back to Dalton, yes McCreery, I'm familiar with that bibliography you mention. Ramos complains that Krueger, without being an 'aborigine of Wales or Australia' cannot perceive the differences between Code A and Code B. Ditto for John Dalton (b. Shrewsbury, 1766-1844). He led a quiet uneventful life, till he got to Jesus College, in Oxford. He joined the cricket team. The fields were covered with a diminute red flower called the 'scarlet pimpernel', and Dalton failed to see them. "Mind them pimpernels", his mates would shout. To no avail. He would not see the pimpernels. Eventually, he was sent to the Nurse, and ultimately to the Imperial College, where it was determined that Dalton found the distinction between red and green _redundant_. Now his name is remembered -- for that very trait of his perceptual scheme DALTONISM was a word "but objected to by English authors on the ground that it associated a great name with a physical defect. See Wartmann's papers on ‘Daltonisme’ in Mem. Soc. Phys. de Genève (1843) X. 273; and (1849) XII. 183.] A name for colour-blindness; esp. inability to distinguish between red and green. 1841 E.
