If the influence of libertarian free will on human behaviour is real, the frequency of certain freely chosen actions will differ from the probability of their occurrences deduced from the statistical calculations and neuroscientific observations and laws. According to D. Pereboom, contemporary science does not prove the efficacy of libertarian free will. According to P. van Inwagen, there is always a random element in free decisions, and hence the effect of the free will remains unknown. Swinburne observes that it is (...) not correct to conclude that libertarian free will has no causal effect in the physical world. One can only conclude that these choices are not neurologically real. People sometimes choose to act on abstract principles, and they can do so on a regular and long-term basis. Consequently, human behaviour can be predicted and explained in terms of personal agency and the reasons upon which the people have chosen to act. Probabilistic calculations strengthen the argument that the best way to explain and predict such rational behaviour is to affirm the efficacy of the libertarian free will, which can overcome neurophysiological motivational states of the body and which guarantees a kind of long-term rational determinism.

The kalām cosmological argument for the existence of God proposed by W. L. Craig (in 1970’s) has been subject to much debate on all sorts of issues related to the existence of God and the beginning of the universe. The goal of the paper is to briefly evaluate several complex questions embraced in the argument in order to show the depth and strength of the argument, and to avoid oversimplification, which one can find in some recent publications. The argument as (...) such does not rely on a single thesis or a theory proposed by a single author. The argument has such a support from different fields that its opponents would need to elaborate a theory with much more explanatory power than the most recent cosmological theories. (shrink)

In his Insight, Lonergan presents a general form of the argument for the existence of God: “reality is completely intelligible, therefore, God exists.” Its framework may be characterized as a Leibnizian version of the cosmological argument from the contingency of empirical reality to the unrestricted act of understanding. The acceptance of Lonergan's argument presupposes familiarity with his theory of being and objectivity. In my analysis, since Lonergan uses heuristic definitions and dialectical method in his justification of the complete intelligibility of (...) reality, the argument invites continuous examination of the proposed alternative metaphysical theories.

The modal argument for the existence of a Cartesian human soul proposed by Richard Swinburne more than thirty years ago, if slightly adjusted and interpreted correctly, becomes a plausible argument for anyone who accepts modal arguments. The difficulty consists in a relatively weak justification of the second premise, of the real possibility of a disembodied existence, as a result of which the argument does not provide a real proof. The argument is best understood in the following terms: Special divine action (...) is excluded from the metaphysical possibilities and only the natural possibilities are considered; the “conceivable” possibility of the existence of a person without a body is interpreted as a metaphysical possibility, and inductive support for its reality is provided by apparent first-person-conceivability of a disembodied existence, detailed descriptions of out-of-body and near-death experiences, a priori trust in introspection in psychology and the cognitive sciences, and by the unity of consciousness and the possibility of its extension to peripersonal space; statements about having a soul or being a material substance are excluded from the domain of the premises; and finally, one accepts the Kripkean principle that having a body or a soul is an essential component of a person. If these conditions are met, the argument is valid, and the conclusion is made more plausible by Swinburne’s modal argument than it would be without it.Argumentum modale pro animae humanae “Cartesianae” existentia, quod R. Swinburne ante plures quam 30 annos proposuit, acceptabile reddi potest cuicumque argumenta modalia non generatim respuenti, si paululum emendetur recteque intelligatur. Omnis huius argumenti diffi cultas consistit in iustifi catione debiliore secundae eius praemissae, quo pacto argumentum ineffi cax redditur. Argumentum vero optime intelligetur his quattuor punctis animadversis: Primo, possibilitas metaphysica non nisi possibilitates naturales comprehendere intelligatur, omni speciali Dei ingerentia exclusa. Secundo, personae possibilitas “conceptibilis” sine corpore existendi intelligatur ut realis possibilitas metaphysica. Cui realitati argumenta favent inductiva tum ex possibilitate imaginandi existentiam sine corpore; tum ex minutatim enarratis testimoniis experiendi status “extra corpus” et “prope mortem”; tum ex fi de fundamentali veritatis introspectionis in psychologia scientiis que cognitivis; tum ex unitate conscientiae ac possibilitate eam in spatium extra corpus extendendi. Tertio, e praemissarum congerie assertiones excludantur quibus homo animam habere vel substantiam materialem esse assumeretur. Quarto, principium S. Kripkii accipiatur, scil. corporis vel animae habitum personae essentialem esse debere. His omnibus servatis argumentum Swinburnii validum evadit, conclusionem suam plus credibilem reddens quam secus esset. (shrink)

In his ’Insight’, Lonergan presents a general form of the argument for the existence of God: "reality is completely intelligible, therefore, God exists." Its framework may be characterized as a Leibnizian version of the cosmological argument from the contingency of empirical reality to the unrestricted act of understanding. The acceptance of Lonergan’s argument presupposes familiarity with his theory of being and objectivity. In my analysis, since Lonergan uses heuristic (second order) definitions and dialectical method in his justification of the complete (...) intelligibility of reality, the argument invites continuous examination of the proposed alternative metaphysical theories.
