 Throughout the twentieth century, and at the beginning of the twenty-first century, psychology exerted and exerts a powerful pull on philosophers who wish to put philosophy on the sure path of a science. Quine famously called for a return to psychologism in the 1960s. Such calls have kept the psychologism accusation alive. Amongst the accused one can find the names of Rudolf Carnap, Michael Dummett, Peter Geach, Nelson Goodman, Thomas Kuhn, John McDowell, Karl Popper, Wilfrid Sellars, and Ludwig Wittgenstein (Kusch 1995, 7). (For an extensive discussion of naturalistic and psychologistic positions from the perspective on twenty-first-century philosophy of logic, see Pelletier et al. 2008. See also Lehan-Streisel 2012.)
