The elemental constituent functions of human minds are not yet known, and the paths to identifying these basic "cognitive acts" are constrained at each end by biology and behavior. A coherent architecture derived bottom-up from brain circuits is proffered. We posit principles and pose questions about architectures, their composition, and their applicability to a described range of formidable tasks, with the primary intent of aiding in setting guideposts and challenges for ongoing architecture studies.
