Arguments For Externalism
Putnam presented a variety of arguments for the externalist position, the most famous being those that concerned Twin Earth. Subsequent philosophers have produced other, related thought experiments, most notably Donald Davidson's swamp man experiment. However, there have been numerous arguments for externalism that do not involve science-fiction scenarios.
Putnam pointed out, for instance, that he has no knowledge that could distinguish elm trees from beech trees. He has precisely the same concept of one as of the other: 'a deciduous tree growing in North America'. Yet when Putnam makes a statement containing the word 'elm', we take him to be referring specifically to elms. If he makes a claim about a property of elm trees, it will be considered true or false, depending upon whether that property applies to those trees which are in fact elms. There is nothing "in the head" that could fix his reference thus; rather, he concluded, his linguistic community, containing some speakers who did know the difference between the two trees, ensured that when he said 'elm', he referred to elms. Putnam refers to this feature of language as 'the division of linguistic labor'.

Famous quotes containing the word arguments:
“There is no assurance of the great fact in question [namely, immortality]. All the arguments are mere probabilities, analogies, fancies, whims. We believe, or disbelieve, or are in doubt according to our own make-up—to accidents, to education, to environment. For myself, I do not reach either faith or belief ... that I—the conscious person talking to you—will meet you in the world beyond—you being yourself a conscious person—the same person now reading what I say.”
—Rutherford Birchard Hayes (1822–1893)
