I focus on how, for me, big questions such as, “How can we tell whether something is true?” were funneled by haphazard influences into specific interests. Classes on logic got me interested in the origins of concepts. Contact with Piaget’s theory of concept acquisition added a developmental dimension. Wondering about the meaning of words led to the problems of opaque contexts like belief reports. A brush with artificial intelligence made me focus on the distinction between implicit and explicit mental representations and consciousness. My thesis supervisor’s expertise in game theory led me to explore children’s perspective-taking. Work with Heinz Wimmer on the false belief task got me firmly entrenched in theory of mind research, focusing on simulation theory as its main opponent. And to get beyond documenting children’s flourishing achievements I turned to mental files theory to understand how perspectival thinking grows from our basic ability to think about objects.
