In this paper we shall introduce the variety FWHA of frontal weak Heyting algebras as a generalization of the frontal Heyting algebras introduced by Leo Esakia in [10]. A frontal operator in a weak Heyting algebra A is an expansive operator r preserving finite meets which also satisfies the equation?? b V, for all a,b? A. These operators were studied from an algebraic, logical and topological point of view by Leo Esakia in [10]. We will study frontal operators in weak (...) Heyting algebras and we will consider two examples of them. We will give a Priestley duality for the category of frontal weak Heyting algebras in terms of relational spaces where is a WH space [6], and R is an additional binary relation used to interpret the modal operator. We will also study the WH- algebras with successor and the WTf- algebras with gamma. For these varieties we will give two topological dualities. The first one is based on the representation given for the frontal weak Heyting algebras. The second one is based on certain particular classes of WH-spaces. (shrink)

To what extent does perceptual language reflect universals of experience and cognition, and to what extent is it shaped by particular cultural preoccupations? This paper investigates the universality~relativity of perceptual language by examining the use of basic perception terms in spontaneous conversation across 13 diverse languages and cultures. We analyze the frequency of perception words to test two universalist hypotheses: that sight is always a dominant sense, and that the relative ranking of the senses will be the same across different (...) cultures. We find that references to sight outstrip references to the other senses, suggesting a pan-human preoccupation with visual phenomena. However, the relative frequency of the other senses was found to vary cross-linguistically. Cultural relativity was conspicuous as exemplified by the high ranking of smell in Semai, an Aslian language. Together these results suggest a place for both universal constraints and cultural shaping of the language of perception. (shrink)

There appear to be a number of general things which can be said about forgiveness. If these are left sufficiently vague they seem to be applicable to all the situations in which the term is used.First, there can be no question of forgiveness unless an injury has been inflicted on somebody by a moral agent. There must be something to forgive; and the injury that is to be forgiven must be one for which a moral agent can be held responsible. (...) One cannot forgive a rock for falling on one's foot or a cougar for attacking one's child—even though a child might kick the rock and a father might shoot the cougar. (shrink)

Reinhold Niebuhr, approaching the ethical field as a theologian rather than as a philosopher, has maintained that the Christian ethic is not single and indivisible, but that, on the contrary, it consists of what one might call an absolute ethic and a kind of interim ethic in which the notion of justice is prominent. Without commenting on Niebuhr's work I wish to put forward a view which, although more general than his, is perhaps not without a superficial resemblance to it.

?Moral Black? and Whitemail? is a study of those modes of action which involve what I propose to call ?a raising of the moral stakes?. Illustration: A wants B to do X, and B wants to do Y; so A creates a situation in which doing Y would either be morally objectionable or more objectionable than it would have been but for A's intervention. Such modes of action include all the varieties of moral blackmail as well as such practices as (...) those of returning good for evil, putting people on trust, and some kinds of non?violent resistance. I try to expose the distinguishing marks of moral blackmail, why it is thought so objectionable, and how it is related to these other practices that also involve a raising of the moral stakes. The study as a whole is intended to underline the ambiguous nature of human action. (shrink)

According to familiar accounts, Rousseau held that humans are actuated by two distinct kinds of self love: amour de soi, a benign concern for one's self-preservation and well-being; and amour-propre, a malign concern to stand above other people, delighting in their despite. I argue that although amour-propre can (and often does) assume this malign form, this is not intrinsic to its character. The first and best rank among men that amour-propre directs us to claim for ourselves is that of occupying (...) 'man's estate'. This does not require, indeed it precludes, subjection of others. Amour-propre does not need suppression or circumscription if we are to live good lives; it rather requires direction to its proper end, not a delusive one. (shrink)
