A way forward on the normalizability problem for the Fine-Tuning Argument

The Fine-Tuning Argument claims that the life-permitting ranges of various parameters are so narrow that, absent theism, we should be surprised that the parameters fall into those ranges. ¶ The normalizability objection is that if a parameter ξ can take any real value, then any finite life-permitting range of values of ξ counts as a “narrow range”, since every finite range is an infinitesimal portion of the full range from −∞ to ∞. Another way to put the problem is that there is no uniform probability distribution on the set of real numbers. ¶ There is, however, a natural probability distribution on the set of real numbers that makes sense as a prior probability distribution. It is related to the Solomonoff priors, but rather different. ¶ Start with a language L with a finite symbol set usable for describing mathematical objects. Proceed as follows. Randomly generate finite strings of symbols in L (say, by picking independently and uniformly randomly from the set of symbols in L plus an “end of string” symbol until you generate an end of string symbol). Conditionalize on the string constituting a unique description of a probability measure on the Lebesgue measurable subsets of the real numbers. If you do get a unique description of a probability measure, then choose a real number according to this distribution. ¶ The result is a very natural probability measure PL (a countable weighted sum of probability measures on the same σ-algebra with weights adding to unity is a... -

Improving on Solomonoff priors Let’s say that we want prior probabilities for data that can be encoded as a countably infinite binary sequence. Generalized Solomonoff priors work as follows: We have a language L (in the original setting, it’ll be based on Turing machines) and we generate random descriptions in L in a canonical way (e.g., add an end-of-string symbol to L and randomly and independently generate symbols until you hit the end-of-string symbol, and then conditionalize on the...

GAME OF THRONES’ FINAL SEASON: WHEN OUR GREAT EXPECTATIONS ARE ILLEGITIMATE [SPOILERS] What follows is a guest post by Sean T. Murphy. Those who haven’t finished the series should beware of spoilers below! Legitimate Artistic Expectations “Almost nothing [showrunners David] Benioff and [D.B.] Weiss do will be enough to please (or appease) everyone.” So says critic Tim Goodman in a recent article in the Hollywood Reporter. It became clearer by the week just how great everyone’s expectations were for the final season of HBO’s Game of Thrones.... Aesthetics for Birds -


Walter Veit’s talk in Bogazici “From Scaffolding to Natural Selection”; May 23, Thursday at 17h; John Freely Building Room #’s 507 and 508; Abstract: Darwin provided us with a powerful tool to explain the evolution of living systems: the Theory of Evolution by Natural Selection. Traditional approaches, however, merely relying on natural selection have proven insufficient to explain the emergence of new levels of selection, i.e. the major transitions. The problem is one of circularity for evolutionary explanations: how to... Hesperous is Bosperous -

WHAT FANDOMS CAN TEACH US ABOUT THE VALUE OF PLOT HOLES AND THE BADNESS OF BAD ARTISTS What follows is a guest post by James Harold, Professor of Philosophy at Mount Holyoke College. Parts of this blog post draw from his article “The Value of Fictional Worlds (or, Why The Lord of the Rings is Worth Reading).” Critics and fans approach certain works (like The Lord of the Rings or Star Wars) very differently. The critics evaluate these works on their own merits, considered as art objects in their own right, while fans consider in... Aesthetics for Birds -


The Hole Argument [Revised entry by John D. Norton on May 17, 2019. Changes to: Main text, Bibliography] What is space? What is time? Do they exist independently of the things and processes in them? Or is their existence parasitic on these things and processes? Are they like a canvas onto which an artist paints; they exist whether or not the artist paints on them? Or are they akin to parenthood; there is no parenthood until there are... Stanford Encyclopedia of Philosophy -
