I summarise Robert Audi's 'Moral Perception.' I concede that there is such a thing as moral perception. However, moral perceptions are culturally-relative, which refutes Audi’s claims that moral perception may ground moral knowledge and that it provides inter-subjectively accessible grounds which make ethical objectivity possible. Audi's attempt to avoid the refutation tends to convert rational disputes into ad hominem ones. I illustrate that with the example of the ethics of prostitution.

Karl Popper lamented the prevalence of dogmatic argument in philosophy and commended the kind of critical argument that is found in the sciences. David Miller criticises the uncritical nature of so-called critical thinking because of its attachment to dogmatic arguments. I expound and clarify Popper’s distinction between critical and dogmatic arguments and the background to it. I criticise some errors in Miller’s discussion. I reaffirm the need for philosophers to eschew dogmatic arguments in favour of critical ones.

I finished my undergraduate degree at Monash University and joined Charles Hamblin’s seminar at the University of NSW in March, 1968. Phil Staines from the University of Newcastle joined at the same time, and Vic Dudman was an established member. Hamblin’s book Fallacies would be published in 1970, but the seminar discussions rarely concerned fallacies. This may have been because Hamblin had been working for so long and so closely with those ideas that he was now ready to turn elsewhere. (...) But I shall argue that the book was only part of a much broader program, other parts of which occupied us in the seminars. Hamblin never explicitly discussed the writing of Fallacies with me, and what follows is an attempt to explain how the book fitted into his overall project as a logician, drawn from his published works and from what I remember of his contributions to the seminar.

Karl Popper's methodology highlights our scientific ignorance: hence the need to institutionalize open‐mindedness through controlled experiments that may falsify our fallible theories about the world. In his endorsement of “piecemeal social engineering,” Popper assumes that the social‐democratic state and its citizens are capable of detecting social problems, and of assessing the results of policies aimed at solving them, through a process of experimentation analogous to that of natural science. But we are not only scientifically but politically ignorant: ignorant of the (...) facts that underpin political debate, which are brought to our attention by theories that, as Max Weber emphasized, can be tested only through counterfactual thought experiments. Public‐opinion and political‐psychology research suggest that human beings are far too unaware, illogical, and doctrinaire to conduct the rigorous theorizing that would be necessary to make piecemeal social engineering work. F.A. Hayek realized that the public could not engage, specifically, in piecemeal economic regulation but failed to draw the conclusion that this was due to a specific type of political ignorance: ignorance of economic theory.

The present paper is an attempt to explore the impact of Karl Popper's ideas on the views of a number of intellectual groups in post-revolutionary Iran. Throughout the text, we have tried to make use of original sources and our own personal experiences. The upshot of the arguments of the paper is that the Viennese philosopher has made a long-lasting impression on the intellectual scene of present-day Iran in that even those socio-political groups which are not in favour of his (...) ideas, especially his model of critical rationalism, have felt the urgent need to make themselves familiar with them. Moreover, many of Popper's ideas have directly or indirectly influenced the thinking of the decision-makers in Iran since 1978. (shrink)

This article was first published in 1982 in Educational Analysis (4, 75–91) and republished in 1998 (Hirst, P. H., & White, P. (Eds.), Philosophy of education: Major themes in the analytic tradition, Vol. 1, Philosophy and education, Part 1, pp. 61–78. London: Routledge). I was then a lecturer in philosophy of education at Sheffield University teaching the subject to Master’s students on both full- and part-time programmes. My first degree was in philosophy, read under D. W. Hamlyn and David Cooper (...) and, given their interests, inevitably emphasized the philosophy of language, in particular the work of Wittgenstein in this field. When I subsequently turned my attention to the philosophy of education it seemed obvious to me that there were serious problems with Professor Peters’ approach to language, and I had particular difficulties with his approach to criteria, meaning theory and what seemed an odd interpretation of a transcendental argument. This article thus set out to show that the then dominant form of philosophy of education seemed not to take account of developments in the philosophy of language that preceded Professor Peters’ early work by at least a decade and which cast serious doubt on the enterprise as it was then understood. As the articles in the 1998 collection indicate, I was not alone in thinking there was something amiss, although at the time I seemed to be ploughing a somewhat lonely furrow. In revisiting this early article some 30 years after it was first published I have found to my surprise that there is little I would now change, although I have been forcibly reminded of the very lively discussions Professor Peters and I had over these issues. The fact that there is little I would now add to, or subtract from, my critique is in itself a telling comment on the enduring and influential legacy of the approach to the philosophy of education that Professor Peters championed so powerfully.

Few, if any, logicians deserve the title 'precursor of modern argumentation theory' more than the largely neglected English logician, Alfred Sidgwick. Sidgwick developed a coherent and original theory of argumentation with a distinctly 'mo dern' flavour. This paper outlines his idea of a 'negative' view of logic, an important aspect of which is the thesis that the distinctions and inference schemata of formal logic should not be applied as criteria of the validity or invalidity of natural language arguments, but rather (...) 'rogatively'--as suggesting the kinds of objections or demands for clarification that are relevant at specific stages of a discussion. (shrink)
