In this article we present a new experimental paradigm: comparative visual search. Each half of a display contains simple geometrical objects of three different colors and forms. The two display halves are identical except for one object mismatched in either color or form. The subject's task is to find this mismatch. We illustrate the potential of this paradigm for investigating the underlying complex processes of perception and cognition by means of an eye‐tracking study. Three possible search strategies are outlined, discussed, (...) and reexamined on the basis of experimental results. Each strategy is characterized by the way it partitions the field of objects into “chunks.” These strategies are: (i) Stimulus‐wise scanning with minimization of total scan path length (a “traveling salesman” strategy), (ii) scanning of the objects in fixed‐size areas (a “searchlight” strategy), and (iii) scanning of object sets based on variably sized clusters defined by object density and heterogeneity (a “clustering” strategy). To elucidate the processes underlying comparative visual search, we introduce besides object density a new entropy‐based measure for object heterogeneity. The effects of local density and entropy on several basic and derived eye‐movement variables clearly rule out the traveling salesman strategy, but are most compatible with the clustering strategy.

"Individuum und Kosmos in der Philosophie der Renaissance" (1927) schreibt ein Stück philosophischer Problemgeschichte und geht der Frage nach, "ob und inwiefern die Gedankenbewegung des 15. und 16. Jahrhunderts bei aller Mannigfaltigkeit der Problemansätze und bei aller Divergenzen der Lösungen eine in sich geschlossene Einheit bildet". Provoziert durch Burckhardts Renaissancestudie, die die Philosophie der Zeit unberücksichtigt läßt, versucht Cassirer nachzuweisen, daß auch die Renaissancephilosophie Teil einer "geistigen Gesamtbewegung" ist und eigene systematische Mittelpunkte besitzt.
