independent researcherSome words in my paper:
T(hj|ei)--fuzzy truth function of a predicate hj.
T(hj)--logical probability or average thue-value of a predicate hj.
Popper defined Testing severity and Verisimilitude (1963/2005, 526, 534). Since Logical Probability and Statistical Probability are not well distinguished by him, his definitions are not satisfactory. The author suggests defining log [1/T(hj)] as testing severity, and T(hj|ei)/T(hj) as verisimilitude. In terms of Likelihood method, P(ei| hi is true)/P(ei) =T(hj|ei)/T(hj) is also called standard likelihood. So, we may say Semantic information = log (Standard likelihood) = log (Verisimilitude)=Testing severity - Relative deviation
If negative verisimilitude for lies or wrong predictions is expected, one may also define verisimilitude by log [T(hj|ei)/T(hj)].
The figure 8 in the paper shows how positive and negative degrees of believe affect thruthlikeness.Latest replies:

2016-08-08After the publication of this paper, I enjoyed personal communication with Aloysius Martinich and discovered that I misused if and only if in several places of this paper. The corrections are below:
The formula indicates the following:
1. A is relatively identical to the value, but A is not absolutely identical to the value.
2. B is relatively identical to the value, but B is not absolutely identical to the value.
3. The value of A is absolutely identical to the value of B.
4. A is not identical to B.
1. The expression 1 + 3 is relatively identical to the value 4, but 1 + 3 is not absolutely identical to 4.
2. The expression 2 + 2 is relatively identical to the value 4, but 2 + 2 is not absolutely identical to 4.
3. The value of 1 + 3 is absolutely identical to the value of 2 + 2.

Portland State UniversityCan you share your opinion?
University of SydneyI am currently studying objections to modal realism for a section of something I'm writing, and am wondering if people can help me with questions about two related objections which seem important to me. My questions are: are there existing sources for these objections, and if so, what are they?
Reality as a whole could have been different
One objection I would like to find more sources for is the idea that reality as a whole (in the most unrestricted sense) could have been different. Lewis's modal realism leads to the conclusion that the whole system of worlds is the way it is necessarily, but intuitively reality as a whole could have been different, so this is a mark against the theory.
I have found one source for this objection - Williamson's 'Necessary Existents', where he says:
'Even if there are mutually disconnected spatiotemporal systems such as Lewis postulates, they are not the distinctive subject matter of modal discourse. They are simply more of what there is, about which we ... (read more)Latest replies:

2015-02-01Terence Rajivan Edward
University of ManchesterI have noticed a small literature on Okin's objection to libertarianism. But I question whether this should be discussed under the heading of "Okin's objection". A very similar objection has been around for centuries by Robert Filmer, which the author briefly mentions but does not present. Filmer's objection is now discussed under the heading of the paradox of self-ownership.
It says that, given common knowledge, we cannot endorse both these propositions, which are essential to (standard?) libertarianism:
(1) Each person owns themselves.
(2) Each person owns the products of their labour.
According to Filmer, a person is the product of their parents' labour so they do not own themselves by (2).
Okin's version says that a person is the product of their mother's labour so they do not own themselves. (It seems she does not give a male parent even 0.000001% labour contribution.)
If the focus is mainly on whether a libertarian can say that individuals are self-owners, I feel it is unfair to discus ... (read more)Latest replies:

Hokkaido UniversityI was often thinking about the thread title question while I worked on the ontology of artworks such as a piece of drama or music. Some philosophers show a positive response to the type view of artworks according to which an artwork is a type and its performances are the tokens. (By the word of "type", here I mean an entity that can have its example(s) like universal.)
What about fictional characters then?
I, at first thought, tended to support the particular view of characters.
Yet the type view may be a more plausible position for some reasons.
One of them can be understood easily when you look at the case that many actors have ever played the role of Hamlet in their own ways. It may be natural that their performances are considered as tokens of the Hamlet-type.
Besides, trademark protection for fictional characters like Disney's may imply the idea that they are types. They seem to think the characters have their tokens, and then to prevent a third party from producing some token ... (read more)Latest replies:

Université du Québec à Montréal
University of Southampton(1) That sentient life will one day come to an end is no solace for those sentients existing and suffering today.
(2) Whether it is better to have been or not to have been is a Cartesian koan I can ponder concrerning myself, but not one I have a right to decide concerning another sentient that is or has been; all the less right have I to create or support the creation of another sentient, out of nothing.
(3) Pain and pleasure are incommensurable; only pain is pertinent to moral musings like these: No number of orgasms (for me) compensates for one fallen sparrow; and, again, the sparrow’s pains or solaces are not for me to weigh -- for the sparrow.
(4) Christianity is particularly self-righteous and presumptuous on such questions, always ready to sanction temporal risk and suffering for the bodies of others for the salvation of their immaterial, immortal souls, sub specie aeternitatis.Latest replies:

Brown UniversityHi Jack,
Nice paper!. However, if I may, I wasn't convinced by your response to objection five. The objection, I take it, is that the intuitions you are marshaling about incoherence derive from a non-moral standpoint, that is, they are intuitions that arise when one is doing metaethics and not when one is actually moralizing. And it seems undeniable that Moore paradoxical sentences are straightforwardly bizarre when uttered by persons in the context of actual moralizing (just imagine actually having the relevant conversation). At the outset of your paper, you correctly note that expressivism is a theory about actual moralizing, so it seems like this is one objection to which you should be very sensitive. You respond:
This is not really a rejection of C3, but a rejection of C1, since it admits that it is not always the case that affective or conative attitudes are expressed by moral assertions. If non-cognitive mental states are only sometimes expressed by moral assertions, then the clai ... (read more)

Brown UniversityHi Professor Demetriou,
I've just read the draft of your paper, and I really enjoyed it, especially the bits where you complicate the somewhat simplistic just-so cultural-evolutionary story provided by Ross and Nisbett. One rarely sees such deep engagement with actual anthropological data in moral-philosophical papers about disagreement, and I think your reflections here are a valuable contribution to this literature.
However, I have a question about the "pluralism" that is on offer, which is "a view urging the moral correctness of multiple and mutually irreducible comprehensive ethical outlooks , each suited to its own dimension of social life ." A familiar worry emerges here, which is that you are covertly drawing on a kind of monism which serves to make each of the competing moral systems appear attractive. The trouble begins with the word "suited": what does it mean to say that a moral outlook is "suited" t ... (read more)

University of YorkFor anyone interested, I've written up a brief critique of this paper at Philosophy, et cetera.
2012-11-12I am delighted that someone of Kitcher's ability has tackled the meta-ethical implications of understanding morality as an evolutionary adaptation. Further, Christine Clavien has advanced that good cause by providing an inspiringly insightful and clear review of important implications of his work.
However, the science of the matter actually supports a much stronger hypothesis than Kitcher's "morality evolved to overcome altruism failures".That stronger hypothesis may have different meta-ethical implications.
Relevant criteria for scientific truth regarding morality as an evolutionary adaptation Include explanatory power for descriptive facts and puzzles, no contradiction with known facts, simplicity, and integration with the rest of science. By these criteria, a superior hypothesis can be stated as "morality overcomes a universal cooperation-exploitation dilemma by motivating or advocating altruistic cooperation strategies". That is, morality is composed of assemblies of biolog ... (read more)Latest replies:

2012-08-08Excellent paper first and foremost Mr. MacLeod! As I was reading your thoughts on plurality and the nature of the individual conscious, it made me think of the ideal of Solipsism.
