 Jean Piaget’s (1933) well-known theory of cognitive development suggests that prior to age 11 or 12, most children are not capable of philosophical thinking. This is because, it holds, prior to this time, children are not capable of “thinking about thinking,” the sort of meta-level thinking that philosophical thinking requires. This level of cognitive development includes analogical reasoning about relationships, such as: “Bicycle is to handlebars as ship is to rudder, with ‘steering mechanism’ being the similar relationship” (Goswami, p. xxi). However, there is a solid body of psychological research that indicates Piaget’s account seriously underestimates children’s cognitive abilities (Astington, 1993; Gopnik, et al., 1999; Gopnik, 2009).
