We are pleased to announce the public launch of the 2020 PhilPapers Survey.  The survey is a follow-up on the 2009 PhilPapers Survey, which was conducted in November 2009.  As with the previous survey, the primary aim of the survey is to discover information about the distribution of philosophical views among professional philosophers in the English-speaking world.  Everyone is welcome to take the survey (whether they have taken the 2009 survey or not). 

The survey includes 100 questions in total.  You will be asked to answer 50 questions, each giving a choice between 2 or more views on a philosophical issue (for example, "Analytic-synthetic distinction: Yes or no?"; "Mind: physicalism or non-physicalism?"). At the end of the survey you will also be given the option to answer the other 50 questions. Respondents must indicate that they accept or lean toward one of the options or can give one of a variety of "other" answers. Following the model of the 2009 s ... (read more)


Today (January 28, 2019) is PhilPapers' tenth birthday. PhilPapers has grown enormously since its modest beginnings at the ANU. In the first months, we had only a few thousand users. Now we have hundreds of thousands. We started by indexing a relatively small number of articles that were readily available online. Now we have by far the most complete index of the philosophical literature with 2.4 million entries.

In the first years, it was just one person doing all the technical work. Now we have a robust and growing team at the Centre for Digital Philosophy. We're very grateful for all the work that everyone has put into PhilPapers, from our 600 or so category editors and our tens of thousands of casual contributors to the developers that have contributed code and the organizations that have supported them. We're enthusiastically looking ahead to what we can achieve as a community over the next ten years.

By the way, everyone is welcome to join us for a special session at the upcoming Pacific ... (read more)

We have just launched a beta testing version of PhilPeople, a directory and social network for philosophers developed by the PhilPapers Foundation with support from the American Philosophical Association. Visit the site to find out more!

In the coming months, we will launch PhilPeople, a new service from the PhilPapers Foundation developed with the support of the APA.  PhilPeople will be a searchable database of philosophers.  It will have an associated search engine that enables searches on a number of dimensions (e.g. by areas of specialization, location, and demographic features).  PhilPeople will also provide a profile page to any philosopher who wants one, with links to their publications on PhilPapers.  It will include social networking features.  It will also include an associated database of academic departments of philosophy, with searchable information about each of these departments.

PhilPeople will have many benefits for the philosophical community.  For individual philosophers, it will provide a way of showcasing your research, making information about you and your work available to the broad community, and helping you to network with other philosophers.  For those planning conferences and events, it w ...

We're pleased to announce the launch of a new site: PhilArchive

As its name indicates, PhilArchive is an open access e-print archive for philosophical works.  PhilArchive is a relaunch and rebranding of the archive service that has been present within PhilPapers since 2009.  The archive service has been widely used, but we have found that some philosophers are unaware of it because of its location within PhilPapers.  We anticipate that the new PhilArchive website will significantly increase awareness and use of the service.  It will also help to logically separate PhilPapers open access content (which is completely free to all) from its indexing service (for which we ask universities to pay a fee).

At launch, PhilArchive includes the 27,000 works already in the PhilPapers archive, making it by far the largest open access archive in philosophy.  PhilPapers and PhilArchive will remain tightly integrated, with all archived papers on one service automatically appearing on the other service ...

We are pleased to announce the launch of a new look for PhilPapers. We have a new logo and a new design to go with it. The new design is more functional and more mobile-friendly.

Our new logo is the winning submission to last year's PhilPapers logo design contest. The winners are Andrea Andrews and Meghan Driscoll from Florida (a link to their web pages has been added to the footer of the site for those who might be interested in working with them). We received about 300 submissions to the contest, many of which were excellent and very professional. The PhilPapers board chose finalists and then polled hundreds of people to choose the winner. We had to select just one design, but we would like to thank all the participants for their excellent contributions. We're lucky to have such a supportive community for this service.

In the weeks and months to come we will be announcing a number of exciting new services. We look forward to sharing these with you.

Where should this thread be placed? Cognitive Sciences, along with my other threads about vision and other brain processes? Or by Physical Sciences, along with the countless myths on which contemporary science is built?

Light is a subjective phenomenon, only known to living creatures as far as we can tell. But it is also a physical phenomenon that stands at the basis of modern science. The way physicists understand light is since du Broglie (1925) the way they understand matter. From gravitational waves to an expanding universe, all depends on how we interpret light phenomena. To change the perception of light in science is to change science itself.
However tempting that maybe, my objectives are much less ambitious.

I've recently rewritten my critique of Alvin Plantinga's persuasive modal version of the argument for the existence of God. I would be pleased for readers to review this draft version and let me know if I've made any basic logical blunders.

In this essay, I uncover both the strengths and weaknesses of Plantinga's argument. I conclude that while the argument is probably formally valid, it is ultimately unsound. I argue that it's only non-analytic premise is not only false, but necessarily so. You can read the draft version of my essay at

A thread of mine is being spammed by Pieter, and after one response from him all I get are posts in my thread The Logic of Physics: Some Problematic Concepts which have nothing to do with said thread. The people responsible at Philpapers apparently do not care about this thread pollution. In fact I know of an illustrious person who he is probably very happy of such a system glitch. If glitch it is. I won't be the first time I have been the object of such bully practices. As you all know three of my threads have been deleted already, and I won't mention numerous other incidents that hinder me as a user of this forum. You would expect the people responsible for this forum to simply ban me if they consider me an undesirable member. Somehow they do not have the balls. So, what of it, Goliath? Do you want to fight it out in the open, of will you stick to your sneaky tricks?

Chapter One
The first lines sound very strange coming from the founder of wave theory since they consecrate the standing of the opposite view, Geometric Optics:
"As happens in all the sciences in which Geometry is applied to matter, the demonstrations concerning Optics are founded on truths drawn from experience." Huygens sees therefore no conflict between his new approach and Optics which are based on the behavior of particles of light. Einstein's wave-particle duality was certainly nothing new!
Huygens therefore does not doubt the validity of optical laws that say that light travels in straight lines, that the angles of incidence and reflection are equal or that refraction obeys the law of sines.
That is all and well, but what is the relation between those particles that make up light, and those waves that the same part ... (read more)

I worry that I may have missed something and my apologies if so, but I can find no global category for my writings. The topic is usually nonduality, either directly or as the general context, yet there is no category for this. I do not wish to use the 'Idealism' category since it is not a mind-only theory, nor 'Monism' since it is not a reduction to a numerical one. 

Nondualism is an ancient and firmly-established position that should be distinguished from most forms of Idealism and Monism. Yet there is nowhere to place essays on this topic. At present I am forced to use 'Metaphysics. Misc.', which makes little sense given the respectability, importance and global popularity of my view.  

The absence of such a category means that writing cannot be collected together and browsed under a common heading and cannot be searched for by those who wish to familiarise themselves with this view.

It also suggests that there is a blind-spot in the approach to philosophy being adopted here. I can und ... (read more)

Can someone explain to me how to make sense of direct realism, more precisely : how can one claim that to perceive is to have direct access to the object itself if we grant that perceiving is the end product of a certain pattern of neurons firing ?

I can understand direct realism on aristotelian grounds where an objective form leaves the object and penetrates the intellect, but if firing neurons are involved, aren't we obliged to say that the brain reconstructs the "thing in itself" ? (I understand also the problems involved with the theory of sense-data and the motivations that originate from physicalism : my question is purely regarding the constraints imposed by basic neurological ideas).

Aristotle claimed that the supralunar realm was composed solely of ether. But did he believe the moon was also made only of ether or did he express doubt about this ? And if he did believe the moon was made solely of ether, how did he explain away the imperfections of the moon which can be seen by the naked eye ?
