SummaryA new form of expiricism has developed recently which drives a wedge between the principles that science alone will provide a true account of reality and that any such account must be grounded in observation. These empiricists hold firm to the first principle, but have qualified adherence to the second. Using arguments like Putnam's Twin Earth scenario, they contend that a search for reality must go beneath the observable to find the microstructure of substances . Their arguments are fallacious and (...) are susceptible to definite counter‐examples, as the author shows. (shrink)
