This is a tricky question, and it can be difficult to see how one might even begin to address it. Faced with an issue like this one, where exactly should we look for evidence? |
Though philosophers have pursued numerous approaches here, one of the most important and influential is to begin with certain facts about people’s ordinary moral practices. The idea is that we can start out with facts about people’s usual ways of thinking or talking and use these facts to get some insight into question... |
Thinkers who take this approach usually start out with the assumption that ordinary thought and talk about morality has an objectivist character. For example, the philosopher Michael Smith claims that |
we seem to think moral questions have correct answers; that the correct answers are made correct by objective moral facts; that moral facts are wholly determined by circumstances and that, by engaging in moral conversation and argument, we can discover what these objective moral facts determined by the circumstances ar... |
And Frank Jackson writes: |
I take it that it is part of current folk morality that convergence will or would occur. We have some kind of commitment to the idea that moral disagreements can be resolved by sufficient critical reflection – which is why we bother to engage in moral debate. To that extent, some sort of objectivism is part of current ... |
Then, once one has in hand this claim about people’s ordinary understanding, the aim is to use it as part of a complex argument for a broader philosophical conclusion. It is here that philosophical work on these issues really shines, with rigorous attention to conceptual distinctions and some truly ingenious arguments,... |
If we really want to go after these issues in a rigorous way, it seems that we should adopt a different approach. The first step is to engage in systematic empirical research to figure out how the ordinary practice actually works. Then, once we have the relevant data in hand, we can begin looking more deeply into the p... |
Just in the past few years, experimental philosophers have been gathering a wealth of new data on these issues, and we now have at least the first glimmerings of a real empirical research program here. But a funny thing happened when people started taking these questions into the lab. Again and again, when researchers ... |
For a nice example from recent research, consider a study by Adam Feltz and Edward Cokely. They were interested in the relationship between belief in moral relativism and the personality trait openness to experience. Accordingly, they conducted a study in which they measured both openness to experience and belief in mo... |
Geoffrey Goodwin and John Darley pursued a similar approach, this time looking at the relationship between people’s belief in moral relativism and their tendency to approach questions by considering a whole variety of possibilities. They proceeded by giving participants mathematical puzzles that could only be solved by... |
Taking a slightly different approach, Shaun Nichols and Tricia Folds-Bennett looked at how people’s moral conceptions develop as they grow older. Research in developmental psychology has shown that as children grow up, they develop different understandings of the physical world, of numbers, of other people’s minds. So ... |
So there we have it. People are more inclined to be relativists when they score highly in openness to experience, when they have an especially good ability to consider multiple possibilities, when they have matured past childhood (but not when they get to be middle-aged). Looking at these various effects, my collaborat... |
To really put this hypothesis to the test, Hagop Sarkissian, Jennifer Wright, John Park, David Tien and I teamed up to run a series of new studies. Our aim was to actually manipulate the degree to which people considered alternative perspectives. That is, we wanted to randomly assign people to different conditions in w... |
Participants in one condition got more or less the same sort of question used in earlier studies. They were asked to imagine that someone in the United States commits an act of infanticide. Then they were told to suppose that one person from their own college thought that this act was morally bad, while another thought... |
Since your classmate and Sam have different judgments about this case, at least one of them must be wrong. |
Participants in the other conditions received questions aimed at moving their thinking in a different direction. Those who had been assigned to the “other culture” condition were told to imagine an Amazonian tribe, the Mamilons, which had a very different way of life from our own. They were given a brief description of... |
Since your classmate and the Mamilon have different judgments about this case, at least one of them must be wrong. |
Finally, participants in the “extraterrestrial” condition were told about a culture that was just about as different from our own as can possibly be conceived. They were asked to imagine a race of extraterrestrial beings, the Pentars, who have no interest in friendship, love or happiness. Instead, the Pentars’ only goa... |
Since your classmate and the Pentar have different judgments about this case, at least one of them must be wrong. |
The results of the study showed a systematic difference between conditions. In particular, as we moved toward more distant cultures, we found a steady shift toward more relativist answers – with people in the first condition tending to agree with the statement that at least one of them had to be wrong, people in the se... |
Note that all participants in the study are considering judgments about the very same act. There is just a single person, living in the United States, who is performing an act of infanticide, and participants are being asked to consider different judgments one might make about that very same act. Yet, when participants... |
But now we face a new question. If we learn that people’s ordinary practice is not an objectivist one – that it actually varies depending on the degree to which people take other perspectives into account – how can we then use this information to address the deeper philosophical issues about the true nature of morality... |
The answer here is in one way very complex and in another very simple. It is complex in that one can answer such questions only by making use of very sophisticated and subtle philosophical methods. Yet, at the same time, it is simple in that such methods have already been developed and are being continually refined and... |

Getting the DID number from a CallCentric SIP trunk for FreePBX |
I’ve got a few DDI numbers from CallCentric all around the world (UK, US, Australia) and couldn’t figure our how to setup an ‘Inbound Route’ in FreePBX that used the number that had been dialled to route the call. |
It turns out that you need to extract the number from the ‘SIP header’ information and there’s no setting in FreePBX to do this so it means hacking at the Asterisk config files just a little. |
There are a few methods for doing this but these instructions should work for FreePBX/Asterisk – |
When setting up your ‘SIP trunk’ in FreePBX under ‘PEER DETAILS’ you want to put the line – |
“context=custom-get-did-from-sip” |
then you need to edit the file /etc/asterisk/extensions_custom.conf and add the following lines – |
Introduction |
============ |
Blood-borne pathogens first encounter the adaptive immune system in the marginal zone region of the spleen where the convergence of innate and adaptive immune mechanisms insures an early and effective response to pathogen antigens ([@bib1], [@bib2]). Both thymic-independent and -dependent responses are elicited in resp... |
Materials and Methods |
===================== |
Mice. |
----- |
C57BL/6 mice obtained from The Jackson Laboratory were used as WT mice and controls unless otherwise stated. Founders of SHIP-deficient mice were provided by G. Krystal (Terry Fox Laboratory, BC Cancer Agency, Vancouver, Canada; reference [@bib18]) and Btk-deficient mice were purchased from The Jackson Laboratory. Op/o... |
Antibodies and Reagents. |
------------------------ |
For histological examination 6-μM frozen sections were stained, and for FACS^®^ analysis erythrocyte-depleted spleen cells were used. Macrophages were detected using MOMA-1, MARCO Abs from Serotec, and ER-TR9 from Accurate Chemical & Scientific Corp. Abs to CD1d, B220, CD19, CD21/CD35 (CRI/II), CD23, MAC-1, anti--rat a... |
Conditional Targeting of SHIP. |
------------------------------ |
Floxed SHIP mice were created by insertion of loxP sites flanking the 10th and 11th exons (see [Fig. 2](#fig2){ref-type="fig"} a) of the SHIP gene. The targeting vector was introduced into embryonic stem (ES) cells by electroporation and clones were selected with neomycin and ganciclovir and verified by Southern blot a... |
Results and Discussion |
====================== |
Mice deficient in the inhibitory signaling molecule SHIP display pleiotropic defects in macrophages, NK cells, and lymphocytes ([@bib18], [@bib22]). A prominent feature of these mice is their splenomegaly resulting from dysregulation of myeloid proliferation. As seen in [Fig. 1](#fig1){ref-type="fig"} Figure 1.SHIP-def... |
In B cell lines it has been shown that SHIP functions as a negative regulator of cellular activation by regulating the association of the positive signaling kinase Btk with the membrane, thus raising the threshold required for stimulation ([@bib23]). It does so by hydrolyzing PIP~3~, the substrate for Btk association w... |
These results suggested that MZMOs might be critical to the organization of the white pulp nodule and localization of MZBs in this structure. To test this directly we exploited the observation that MZMOs can be ablated by their preferential ingestion of macrophage-depleting liposomes ([@bib30]). At a low concentration ... |
