The paper deals with an argument reported by Razi (d. 1210) that was used to attempt to refute the immateriality of human nature. This argument is based on an epistemic asymmetry between our self-knowledge and our knowledge of immaterial things. After some preliminary remarks, the paper analyzes the structure of the argument in four steps. From a methodological point of view, the argument is similar to a family of epistemological arguments (notably, the Cartesian argument from doubt) and is vulnerable to (...) the same objection that can be raised against that form of reasoning. The last section points out that the argument can be used indirectly to highlight the weakness in some arguments for the claim that there is something immaterial in human beings. (shrink)

This essay deals with a selected part of an epistemological controversy provided by Tūsī in response to the skeptical arguments reported by Rāzī that is related to what might be called "intellectual skepticism," or skepticism regarding the judgments of the intellect, particularly in connection with self-evident principles. It will be shown that Rāzī has cited and exposed a position that seems to be no less than a medieval version of empiricism. Tūsī, in contrast, has presented us with a position that (...) rejects such empiricism. The comparative aim of this essay is to draw attention to some similarities as well as some points of divergence between the kind of skeptical debate we are focusing on here, and some relevant epistemological discussions in the later traditions in the West.

In an earlier paper in Theoria, I discussed an argument based on the idea of “soul-switching” that attempted to undermine the immaterialist account of human beings. The present paper deals with a parity argument against that argument in which the idea of “body-switching” plays a pivotal role. I call these two arguments, that have been reported by Razi (d. 1210), respectively “the soul-switching argument” and “the body-switching argument”. After some introductory remarks, section 2 of the paper describes the structure of (...) the latter argument. Section 3 considers some philosophical discussions in the ancient, modern, and contemporary eras in which the idea of body-switching (or some similar conception) plays a major role. In the following section 4, some criticisms of the argument are discussed and a general response that is meant to cover a broad range of objections is considered. This paper shows that the body-switching argument reported by Razi is a methodological antecedent of several contemporary arguments in defence of substance dualism. (shrink)

This article deals with an argument reported by Razi (d. 1210) that attempted to undermine the immaterialist position about human nature. After some introductory remarks and explanation of the conceptual background, the article analyses the structure of the argument, with special attention to the idea of soul-switching.’ Some comparisons are made between the argument reported by Razi and a number of arguments from modern and contemporary eras of philosophy. One section is devoted to the critique of the argument and its (...) conceptual basis. This article shows that the argument reported by Razi is a methodological antecedent of a family of contemporary epistemological arguments against substance dualism. It is also shown that discussion of the argument could be useful to highlight a weakness in some, but not all, versions of immaterialism about human nature. (shrink)

The notion of creatio ex nihilo has become a doctrine firmly established in the three Abrahamic religions (i.e., Christianity, Judaism and Islam). Almost all groups of Islamic thinkers accept the truth of the createdness (creatio) of the universe, and that it is preceded by its “non-existence” (ex nihilo). However, there is a diversity of opinions as to whether the concept of creatio ex nihilo is compatible with alternative accounts of the origin of the physical world, and this diversity is particularly (...) marked between Islamic philosophers and kalam theologians (Mutakallimun). Three major factors, independently or together, play a fundamental role on how Islamic scholars deal with this very issue: (a) their views of the physical world; (b) their approaches to the divine attributes; and (c) their understandings of the teachings of their religion. The aim of this chapter is to investigate whether four different notions of creatio ex nihilo espoused by different Islamic thinkers are compatible with seven alternative accounts of the origins of the universe (five philosophical/theological doctrines – first level of compatibility; and two possible interpretations of a modern scientific theory – second level of compatibility).

This is the original Arabic text of three philosophical questions raised by Tusi (1201–1274) in his letter to Khusrawshahi (1184-1254). These critical questions are related to three main fields of philosophy: Philosophy of Nature, Philosophical Psychology (or Philosophy of the Soul) and Philosophical Theology which is traditionally subsumed as one of the proper subtopics of Metaphysics. Although Tusi did not receive any recorded response from Khusrawshahi, his short letter attracted considerable scholarly attention and received some remarkable responses, in later Islamic (...) philosophy and thus provided an exemplar of the traditional technique of debating by way of “question-answer” correspondence.

In recent years, philosophers have shown a rapidly increasing interest in the problem of consciousness and it is arguably the central issue in current interdisciplinary discussions about the mind. Any convincing theory of consciousness has to account for the perplexing aspects of human self-consciousness. This paper deals with Ibn Sina’s view on the human self-consciousness with special reference to his well-known “Flying Man” thought experiment. In a brief comparative discussion, we will consider some of the parallels between Ibn Sina’s account (...) of “consciousness of consciousness” and the contemporary “higher-order” theories of consciousness. An important point of divergence between Ibn Sina’s line of argument and Descartes’ method over the problem of self-consciousness will be examined, as well. Further, Thomas Nagel’s famous view on the subjective character of conscious experience will be mentioned and compared with the implications of Ibn Sina’s dictum that “our self-consciousness is identical to our existence”.
