One of the most commonly-raised objections to the design argument is the so-called “who designed the designer?” objection, which charges that any designer invoked to explain complexity in the universe will feature complexity of its own, and thus require explanation in terms of design. There are two distinct versions of this objection in the contemporary literature, with it being couched in terms of: (1) Complexity of designer: a designer exhibits complexity, which calls for explanation in terms of design; (2) Complexity (...) of ideas: a designer’s ideas exhibit complexity, which calls for explanation in terms of design. To each of these versions of the objection there corresponds various responses from proponents of design. These proponents adopt a very particular strategy when crafting their responses: they argue that the objection can be neutralised simply by appealing to one or more of God’s attributes. In this paper I argue that this strategy is inapt, and unable to yield a successful response to either version of the objection. I also argue that a more promising way of tackling the objections is to identify their own peculiar weaknesses, for once these are exposed the objections cease to be a credible threat to the design hypothesis.

En este artículo se plantean las siguientes preguntas: primero, ¿es Peirce un realista científico? Segundo, ¿han sido relevantes las ideas de Peirce para la defensa contemporánea del realismo científico? Y tercero, ¿está el realismo científico peirceano comprometido con una metafísica de la ciencia? La respuesta a tales preguntas es positiva. En el argumento se apela tanto a consideraciones de los manuscritos de Peirce como al debate contemporáneo sobre realismo científico. Luego de algunas observaciones introductorias en la primera sección, se expone (...) brevemente en la segunda sección el realismo científico en la versión de Psillos. En la siguiente sección se argumenta que la noción de abducción peirceana ha resultado crucial en la defensa contemporánea del realismo científico. En la cuarta se exponen algunos lineamientos de la metafísica de la ciencia del realismo científico peirceano, a saber, de creencia natural y ley de la naturaleza. En la quinta sección son resumidas las razones principales expuestas en este artículo para sostener que Peirce es un realista científico cuyas ideas han resultado de vital importancia en el debate actual.

Debates on the metaphysics of science have steadily gained momentum over the last decade or so. This appears to illustrate a case of philosophers’ realisation that metaphysics—and theoretical philosophy overall—largely depends upon the sciences and has a good deal to learn from them. Recent literature on this, in fact, has reached an unforeseen high level of refinement in the arguments and a very much desirable precision in the consequences that we can derive from examining the interplay currently undergoing between science (...) and metaphysics. The editors of the volume under review have certainly done a great work by compiling some fruitful and novel contributions to our understanding of issues such as the aim and scope of the metaphysics of science, laws of nature, causation, and natural kinds, which are amongst the most heatedly discussed topics in the arena.The structure of the volume is as follows: “What is the metaphysics of science?” ; “Measurements, la ..

This article reviews the book "Scientific Realism and the Rationality of Science" by Howard Sankey.

Section 2 will begin by formulating Reichenbach’s principle of common cause in a more general way than is usual but in a way that makes the idea behind it a lot clearer. The way that Salmon has pushed the principle into the services of scientific realism will be explained in terms of an example, van Fraassen objects, Salmon modifies his stand and van Fraassen rejoins - all in section 2. (See van Fraassen 1980, chapter 2).In this episode I think van (...) Fraassen right in claiming - against Salmon that there is no categorical imperative for common cause explanation, and I add my own examples in section 3. The first example ‘is the explanation of the correlation between the equilibrium positions of two objects on a balance in terms of their property of “mass” and the law of moments. (shrink)

William Whewell’s philosophy of scientific discovery is applied to the problem of understanding the nature of unification and explanation by the composition of causes in Newtonian mechanics. The essay attempts to demonstrate: the sense in which ”approximate’ laws successfully refer to real physical systems rather than to idealizations of them; why good theoretical constructs are not badly underdetermined by observation; and why, in particular, Newtonian forces are not conventional and how empiricist arguments against the existence of component causes, and against (...) the veracity of the fundamental laws, are flawed.

Sober (1984) has considered the problem of determining the evidential support, in terms of likelihood, for a hypothesis that is incomplete in the sense of not providing a unique probability function over the event space in its domain. Causal hypotheses are typically like this because they do not specify the probability of their initial conditions. Sober's (1984) solution to this problem does not work, as will be shown by examining his own biological examples of common cause explanation. The proposed solution (...) will lead to the conclusion, contra Sober, that common cause hypotheses explain statistical correlations and not matchings between event tokens. (shrink)

Our universe features a harmonious match between laws and states: applying its laws to its states generates other states. This is a striking fact. Matters might have been otherwise. The universe might have been stillborn in a state unengaged by its laws. The problem of nomological harmony is that of explaining the noted striking fact. After introducing and developing this problem, we canvass candidate solutions and identify some of their virtues and vices. Candidate solutions invoke the likes of a designer, (...) axiarchic meta-laws, multiverses, essential causal powers, and Humean laws. (shrink)

En este artículo haré un análisis crítico del debate entre Larry Laudan y algunos defensores del Realismo Epistemológico Convergente. Según esta postura, las mejores teorías científicas exhiben éxito referencial y este rasgo prueba que tales teorías son, al menos, aproximadamente verdaderas. Para Laudan, es irrelevante considerar y tratar a las teorías científicas como si fueran verdaderas. Mostraré que los argumentos de Laudan en contra del Realismo Epistemológico Convergente son bastante plausibles, por lo que la defensa realista en contra de estos (...) argumentos parece no ser exitosa.
