Abstract
Looking back on my intellectual career of nearly a half century, from the 1970s to the 2020s, it is surprising— at least to me—that it was not until I began this memoir that I understood it was all about architectural exploration. Initially this focused on cognitive architectures for integrated minds, such as Soar and Sigma, but increasingly it has also involved architectures of academic disciplines—such as artificial (general) intelligence and computer/cognitive science—that study integrated minds. The theme of this memoir then emerged naturally from understanding this methodology—including a particular perspective on what it means to be an architecture and the continuing importance of exploration—and of its application to this pair of apparently disparate topics. This memoir thus develops this theme and traces it through my career.
