“…1073(Bolles, -1074, writing, for example, "with dramatic clarity" (Brooks, Purser, & Warren, 1964, p. viii) about moral responsibility (Skinner, 1955(Skinner, -1956see Skinner, 1983e, p. 107), Skinner can be difficult to understand. He sometimes used a terse technical style (T. Thompson, 1988, p. 398), changed his perspective (Chiesa, 1992;Coleman, 1984;Iversen, 1992;Moxley, 1998;Scharff, 1982), and can easily be read out of context (Todd & Morris, 1992). As an example of the last point, in writing that "the variables of which behavior is a function ... lie outside the organism, in its immediate environment, and in its environmental history," Skinner (1953a, p. 31) is easily misunderstood to mean that evolutionary history was irrelevant (see Garcia & Garcia y Robertson, 1985), when it was not (see Skinner, 1966c; see also the shaping-sculpting metaphor, Skinner, 1953, p. 91).…”
