Justin Leiber

(1938 - 2016)

"This is a dialogue about the notion of a person, of an entity that thinks and feels and acts, that counts and is accountable. Equivalently, it's about the _intentional idiom_--the well-knit fabric of terms that we use to characterize persons. Human beings are usually persons (a brain-dead human might be considered a human but not a person). However, there may be persons, in various senses, that are not human beings. Much recent discussion has focused on hypothetical computer-robots and on actual nonhuman great apes. The discussion here is naturalistic, which is to say that count and accountability are, at least initially, presumed to be naturally well-knit with the possession of a cognitive and affective life." --Justin Leiber, from the Introduction.

This book, by two philosophers at Bradford University, immediately strikes the American reader with two differences in the British philosophical scene. One is the enveloping commitment to "Davidsonian linguistics" which still seems the central topic for many of Oxford's younger philosophers. In this slim volume Davidsonian semantics is thought to provide that some measure of cross-cultural understanding is possible, that humanistic descriptions of human activity are irreplaceable and unrevisable since action explanation is non-nomothetic though often causal and inferential, that collectives may have expressive but not explanatory autonomy, and that social descriptions are not irredeemably value-laden. Who would have thought Davidsonian semantics had so much blood in it? Though the Tarskian T-Convention requirement is outlined in the short introductory chapter, one is hard put to see any real connection between the insistence on model theoretic and extensional approaches and the subsequent chapters. Though the introduction briefly allows that intensional notions are to be ignored, we are later assured that we may safely ascribe one classical logic to primitives and humans generally since "only at the highly advanced level of theoretical physics has it been found necessary to experiment with different logics". Ignored are those who think mathematics itself requires an intuitionist or intensional understanding. Also ignored are the many linguists who have recently held that the vast majority of sentences in everyday speech require intensional or modal analysis. The authors also use the label "functionalism" for the view that a society is something like a biological organism rather than a collection of rational agents. One finds this usage disconcerting. Much more unfortunate is that the authors seem innocent of the rich philosophical and psychological and neurological work on mental states and psychological explanation that has grown up around the more recent usage of the term.--Justin Leiber, University of Houston.

This vigorously written and clearly argued Bradford Book is a must for anyone interested in intentionality, functionalism, and the status and prospects of scientific and folk psychology. It is a measure of how much has changed in the philosophy of psychology that the familiar arguments--masterfully marshalled and extended here-against the reducibility of everyday psychological statements to statements about brain states within an experimental cognitive science are here, for Stich, arguments against folk psychology. The experimental behaviorists are understood as having issued the revolutionary, and reasonably justified, claim that our everyday folk psychological talk is simply false: false in much the way of demonology in that the things folk psychology talks about simply are not there. What helped us to be less troubled by this claim was analytic or logical behaviorism: folk psychological talk was perfectly viable because it really was just short-hand dispositional talk about behavior. Using beliefs as a central stalking horse, Stich argues, as recent eliminative materialists like the Churchlands, that it may well be that the terms of folk psychology have no referents. In brief, there simply may be no such things as beliefs, any more than there are devils, though of course there are all sorts of interesting phenomena that have led us to talk as if there were such. Beliefs are not in the head, nor anywhere else either.

This is an excellent book for philosophers, and others concerned with natural language and cognition, who have not kept up with post-Aspects work in syntax, in particular with the Extended Standard Theory work on government and binding that relates to anaphora and quantification. It is a direct challenge to those who think that there must be a reasonably clearcut semantic level of description for sentences in natural language, one which is crucial for explaining how we learn, understand, and use natural language. Hornstein argues that the properties of quantification such as relative quantifier scope and pronoun binding in natural language are best explained in purely syntactic terms. "Not only are the explanations best construed syntactically but, more important, the distinctions and concepts needed to articulate them cut against the semantic distinctions one would naturally make". This syntactic theory will, of course, be supplemented in a full theory of language use by pragmatic theories that will assign meaning, force, reference, etc., in particular contexts, given all sorts of real world knowledge. But what we won't have will be a compositional, context insensitive level of semantic description in which true, denotation, object, model, etc., loom large. Though Hornstein is a philosopher, his arguments derive from a linguist's familiarity with recent syntactical work; however, the general line is consonant with Stich's From Folk Psychology to Cognitive Science: The Case Against Belief, in which Stich argues beliefs are so context and intrepretive-stance relative that they cannot be grist for a scientific psychology, which must rather limit itself to syntactical characterizations of sentences in cognition.

Nature's experiments in isolation—the wild boy of Aveyron, Genie, their name is hardly legion—are by their nature illusive. Helen Keller, blind and deaf from her 18th month and isolated from language until well into her sixth year, presents a unique case in that every stage in her development was carefully recorded and she herself, graduate of Radcliffe College and author of 14 books, gave several careful and insightful accounts of her linguistic development and her cognitive and sensory situation. Perhaps because she is masked, and enshrined, in William Gibson's mythic and false Miracle worker, cognitive scientists have yet to come to terms with this richly enlightening, albeit anecdotal, resource

In lieu of an abstract, here is a brief excerpt of the content:Notes and Fragments THE FUTURE PRESENT TENSE by Justin Leiber Perhaps the simplest, most general, and oldest claim about fiction is that it should instruct and entertain. A logical positivist might draw a sharp line between the factual content of a discourse and the pleasurable emotional release available to the auditor. Aristotle straddles this distinction in seeing (dramatic) fiction as imitation of, principally, human action, an imitation which is, Aristotle assures us in Poetics, both naturally pleasurable to perform or to observe performed. The distinction is straddled because for something to be an imitation of something else it must convey some body of rough fact about that thing; and granted various conventions of form and good form, the more accurate, compact, and revealing the imitation, the more the entertainment. Indeed, Aristotle also insists that drama is more universal than history, for the poet depicts what is necessary and probable in human action, while history depicts what is actual, though perhaps improbable, and the historian may not illume what is necessary, representative, exemplary, or prophetic in the mass of supposed actualities. There is a puzzle here in Aristotle's attitude. All humans by nature desire to know is the resolute thesis of the Metaphysics and he suggests there and elsewhere that this desire is a noble one and one whose fulfillment is an important form and ingredient of happiness. In Poetics it is quite clear that both the poet and the audience must have some of the sort of stuff that Aristotle considers fully genuine knowledge, explanatory knowledge, knowledge of universals, for otherwise they could not produce or understand the work as successful (or unsuccessful) imitation of the probable, 203 204Philosophy and Literature necessary, exemplary, etc., in human action. So in entertaining the work inevitably instructs. Aristotle does say that Homer gives in hexameters an imitation of human action, while Empedocles gives in hexameters physical philosophy. But what if Empedocles were providing us psychology? The example could be made more telling if we consider a twentieth-century psychoanalytic Empedocles who tracks or elucidates some generalizations of psychology through giving imagined, or partly imaged, case histories — how would such a work be psychology as opposed to fiction? Imitation (mimesis) wouldn't do thejob, for Aristotle mentions Socratic Dialogue as a form of it. To move to contemporary instances, what may we suppose is the difference between Plato's Republic and Robert Heinlein's Space Cadet? l In Space Cadet, we find some hundred years hence a modernized version of the Platonic Republic, with an elite outgrowth of the United Nations, the "Space Patrol," playing the role of the philosopher kings to the whole earth. Heinlein presents Plato's three-component theory of human psychology and of the meritocratic, tripartite, hierarchic structure of the most real, or healthy, state, and he argues and illustrates the basic Platonic thesis. Ethics is as much an objective science as mathematics, immorality is a form of ignorance (no one knowingly does wrong), and the general solution to the problem of statescraft is the creation of an educational system that will winnow, at level after level, and further educate an intellectual/ethical elite who will monopolize ultimate weaponry and political power, who will use the "divine lie" tojustify their authority, and who will act out of ethical knowledge, not for individual gain. Heinlein gives his account of these matters from the point of view of a Mathew Dobson, a Patrol candidate, who resembles a Candide who finds himself within a reasonable facsimile of the Just State, if not the Best of All Possible Worlds. One concedes that Plato provides us a substantially original, more detailed and coherently worked out set of speculations and theories, while Heinlein provides us a perhaps banal version of these ideas in a sentimental (perhaps fascistic) vision. Similarly, one eagerly concedes that Plato's Republic has played a potent role in European Civilization and the sweep of human thought, while Space Cadet has not. But, plainly, the distinction between a work of philosophy, or of physics, and a (dramatic) fiction or science fiction, cannot be this. One can have unoriginal, false, or impotent works of physics, psychology, or philosophy. So one cannot argue on...

Philosophers concerned with speech acts, or Wittgenstein's uses of language , mostly fix their attention on actions done by issuing just a phrase or short sentence (in the appropriate circumstances with the proper qualifications, feeling, intent, uptake, etc.). "Five red apples" is Wittgenstein's paradigm example in his Philosophical Investigations . "There's a bittern at the bottom of your garden" plays a similar role in J. L. Austin's most central and ambitious essay, "Other Minds." Indeed, as Wittgenstein points out, a single word or gesture may do the job perfectly well, just as an illiterate man can make a valid contract by marking an "X" on a piece of paper. And, of course, in all relevant philosophical respects, a speech act may be written rather than spoken: in his leitmotiv example, Wittgenstein..
