Die Frage, mit der sich Johannes Haag in Erfahrung und Gegenstand auseinandersetzt, lautet: „Auf welchem Grunde beruht die Beziehung desjenigen, was man in uns empirische Vorstellung, d. i. Erfahrung nennt, auf den Gegenstand überhaupt?“ ...

Descartes’ metaphysics lays the foundation for the special sciences, and the notion of consciousness (conscientia) belongs to metaphysics rather than to psychology. I argue that as a metaphysical notion, ‘consciousness’ refers to an epistemic version of moral conscience. As a consequence, the activity on which science is based turns out to be conscientious thought. The consciousness that makes science possible is a double awareness: the awareness of what one is thinking, of what one should be doing, and of the possibility (...) of a gap between the two.

This book examines Aristotle's four causes (material, formal, efficient, and final), offering a systematic discussion of the relation between form and matter, causation, taxonomy, and teleology. The overall aim is to show that the four causes form a system, so that the form of a natural thing relates to its matter as the final cause of a natural process relates to its efficient cause. Aristotle's Four Causes reaches two novel and distinctive conclusions. The first is that the formal cause or (...) essence of a natural thing is not a property of this thing but a generic natural thing. The second is that the final cause of a process is not its purpose but the course that processes of its kind typically take. (shrink)

Avicenna says that intellectual cognition involves the emanation of an intelligible form by the ‘agent intellect’ upon the human mind. This paper argues that in order to understand why he says this, we need to think of intellectual cognition as a special case of a much more general phenomenon. More specifically, Avicenna's introduction of an agent intellect will be shown to be a natural consequence of certain assumptions about the temporality, the completion, and the teleology of the causal processes by (...) which things acquire forms.

Wenn Tugenden Praxisformen sind, dann kann man einiges über Praxisformen lernen, indem man nachsieht, was Tugenden sind. Ich werde dies im Folgenden partiell und indirekt tun, indem ich die sprachliche Form untersuche, in der Aristoteles die ethischen Tugenden beschreibt. Er tut dies im Wesentlichen dadurch, dass er den derart Tugendhaften in der dritten Person Singular beschreibt. Dann werde ich kurz auf die Grenzen von Aristoteles’ Verfahren zu sprechen kommen, indem ich auf eine den Tugenden und anderen Praxisformen inhärente Pluralität hinweise. (...) Eine vergleichbare Untersuchung der sprachlichen Form in der Nikomachischen Ethik ist mir nicht bekannt; die Hinweise auf die Pluralität der Tugend dagegen beanspruchen keine besondere Originalität.
