Explicit atheism is a philosophical position according to which belief in God is irrational, and thus it should be rejected. In this paper, I revisit, extend, and defend against the most telling counter arguments the Kalām Cosmological Argument in order to show that explicit atheism must be deemed as a positively irrational position.

A simple counterfactual theory of causation fails because of problems with cases of preemption. This might lead us to expect that preemption will raise problems for counterfactual theories of other concepts that have a causal dimension. Indeed, examples are easy to find. But there is one case where we do not find this. Several versions of causal decision theory are formulated using counterfactuals. This might lead us to expect that these theories will yield the wrong recommendations in cases of preemption. (...) But they do not. The explanation, I argue, is that the ‘cause’ that has been the target of counterfactual analyses is a specific relation, ‘actual causation’, that is not needed for prospective deliberation. A simple counterfactual theory of causation seems to capture the notion of cause needed for causal decision theory. This shows, in opposition to some critics, that counterfactual theories of causation are not barking up the wrong tree. (shrink)

Plantinga’s The Nature of Necessity (1974) contains a largely neglected argument for the claim that the proposition “God is omnipotent, omniscient, and wholly good” is logically consistent with “the vast amount and variety of evil the universe actually contains” (not to be confused with Plantinga’s famous “Free Will Defense,” which seeks to show that this same proposition is logically consistent with “some evil”). In this paper I explicate this argument, and argue that it assumes that there is more moral good (...) than evil in the cosmos. I consider two arguments in favour of this assumption, proposed by William King and Plantinga respectively, and argue that they are flawed. I then consider a sceptical objection to the assumption due to David Hume, and argue that this objection is at least prima facie plausible. (shrink)

Many things in the natural world work so well that they seem to have been designed. But by what? Could nature itself, by processes including those of evolution, be the designer? Or must their complex structure and function be attributed to some intelligent designer or God? Is natural design compatible with intelligent design? How good is the argument from the presence of design to an intelligent designer? And if we could legitimately infer the probable existence of an intelligent designer from (...) the presence of design in the natural world, what could we then infer about that designer's nature?

In conclusion, then, I think that the refutations proffered by Mackie of thekalām cosmological argument were all too quick and easy. Nor do I think Oppy has succeeded in rehabilitating those refutations.

Graham Oppy has emerged as one of the kalam cosmological argument’s most formidable opponents. He rejects all four of the arguments drawn from metaphysics and physics for the second premiss that the universe began to exist. He also thinks that we have no good reason to accept the first premiss that everything that begins to exist has a cause. In this response, I hope to show that the kalam cosmological argument is, in fact, considerably stronger than Oppy claims, surviving even (...) his trenchant critique. (shrink)

If the contemporary rebirth of the ontological argument had its conception in Norman Malcolm's discovery of a second Anselmian argument it had its full-term delivery as a healthy philosophical progeny with Alvin Plantinga's sophisticated modal version presented in the tenth chapter of The Nature of Necessity. This latter argument has been the centre of a huge body of literature over the last fifteen years, and deservedly so. One is impressed that this version of Anselm's jewel is valid and sound if (...) any is. (shrink)

Most accounts of miracles assume that a necessary condition for an event's being miraculous is that it be, as Hume put it, “a violation of the laws of nature.” However, any account of this sort will be ill-suited for defending the major Western religious traditions because, as I will argue, classical theists should not believe in violations of the laws of nature. In place of the rejected Humean accounts, this paper seeks to develop and defend a Leibnizian conception of miracles (...) on which an event is said to be miraculous just in case we can discover its final cause but not its efficient cause.

Em Warranted Christian Belief (2000), Alvin Plantinga (1932-) desenvolve sua Epistemologia Reformada (Calvinista), com o objetivo de oferecer aval (warrant) para a crença teísta (professada pelas Religiões Abraâmicas: Judaísmo, Cristianismo e Islam) e para a crença cristã clássica (uma crença cristã ecumênica aceita pelos Apóstolos de Cristo, os cristãos primitivos, os pais da Igreja, os ortodoxos, os católicos, os protestantes (os luteranos, os reformados e os arminianos) e os anabatistas). Todavia, o mais natural, que poderíamos esperar de uma Epistemologia Reformada, (...) seria uma epistemologia dedicada às crenças da Cosmovisão Reformada. Sendo assim, a questão norteadora do presente trabalho é: A Epistemologia Reformada de Plantinga é Realmente Reformada? (shrink)
