In this article, I develop a higher-order interpretation of Leibniz's theory of consciousness according to which memory is constitutive of consciousness. I offer an account of Leibniz's theory of memory on which his theory of consciousness may be based, and I then show that Leibniz could have developed a coherent higher-order account. However, it is not clear whether Leibniz held (or should have held) such an account of consciousness; I sketch an alternative that has at least as many advantages as (...) the higher-order theory. This analysis provides an important antecedent to the contemporary discussions of higher-order theories of consciousness. (shrink)

What did Leibniz have to contribute to the philosophy of mind? To judge from textbooks in the philosophy of mind, and even Leibniz commentaries, the answer is: not much. That may be because Leibniz’s philosophy of mind looks roughly like a Cartesian philosophy of mind. Like Descartes and his followers, Leibniz claims that the mind is immaterial and immortal; that it is a thinking thing ; that it is a different kind of thing from body and obeys its own laws; (...) and that it comes stocked with innate truth-tracking intellectual ideas and an epistemically troubling habit of forming confused sensory ideas on the occasion of external corporeal events. Nothing is new. Of course, Leibniz adds unconscious perceptions to the mind in the form of his famous petites perceptions, and he offers a unique solution to the problem of mind-body interaction in the form of his infamous pre-established harmony. In the overall scheme of things, however, these look like minor alterations in a philosophy of mind that the Cartesians had been advocating for some fifty years. Or so it appears. (shrink)

In the absence of any plausible reductionist account of consciousness in nonmentalistic terms, the HOT theory says that the best explanation for what makes a mental state conscious is that it is accompanied by a thought (or awareness) that one is in that state. I discuss HOT theory with special attention to how Leibnizian theses can help support it and how it can shed light on Leibniz's theory of perception, apperception, and consciousness. It will become clear how treating Leibniz as (...) a HOT theorist can solve some of the problems he faced and some of the puzzles posed by commentators, e.g. animal mentality and the role of reason and memory in self-consciousness.

Die folgenden Ausführungen gehen der Frage nach, ob Leibniz die Auffassung vertreten hat, daß nur Geister apperzipieren. Die Untersuchung dieser Frage führt zu neuen Einsichten in die Bedeutung des Begriffs der apperceptio, welcher zu den zentralen Begriffen der Leibnischen Philosophie gehört. Der Aufsatz ist in drei Teile gegliedert: 1. die herrschende Meinung, 2. Gegenargumente gegen diese Meinung, 3. die Bedeutung dieser Argumente fur die herrschende Auffassung.

In God existence is the same as essence; or—the same thing ·put differently·—it is essential for God to exist. So God is a necessary being, ·a being who exists necessarily·.

Leibniz viewed the principle of continuity, the principle that all natural changes are produced by degrees, as a useful heuristic for evaluating the truth of a theory. Since the Cartesian laws of motion entailed discontinuities in the natural order, Leibniz could safely reject it as a false theory. The principle of continuity has similar implications for analyses of Leibniz's theory of consciousness. I briefly survey the three main interpretations of Leibniz's theory of consciousness and argue that the standard account entails (...) a discontinuity that Leibniz could not allow. I argue that the principle of continuity and the textual data favor an interpretation according to which a conscious mental state just is a perception that is distinct to a sufficient degree.

The main aim of this paper is to show that we can extract an elaborate account of phe- nomenal consciousness from Leibniz’s (1646-1716) writings. Against a prevalent view, which attributes a higher-order reflection account of phenomenal consciousness to Leibniz, it is argued that we should understand Leibniz as holding a first-order concep- tion of it. In this conception, the consciousness aspect of phenomenal consciousness is explained in terms of a specific type of attention. This type of attention, in turn, is (...) accounted for in terms of cognitive appetites aiming at knowledge about a repre- sented object by means of initiating cognitive operations on representational content. Furthermore, against the view that Leibniz holds a reifying account, it is argued that Leibniz accepts an epistemic account of phenomenal character. According to this view, the phenomenal character of phenomenally conscious states rests on the con- fusing effect of imperfect acts of attention directed towards representational contents. Holding this view, Leibniz finds fruitful middle ground between contemporary stan- dard positions like higher-order theories, representationalist conceptions, and qualia accounts of phenomenal consciousness. His position possesses resources to meet sev- eral objections these standard accounts are confronted with. (shrink)
