In his paper “Finitism” (1981), W.W. Tait maintains that the chief difficulty for everyone who wishes to understand Hilbert’s conception of finitist mathematics is this: to specify the sense of the provability of general statements about the natural numbers without presupposing infinite totalities. Tait further argues that all finitist reasoning is essentially primitive recursive. In this paper...

Some philosophers have replied to Leibniz’s “shift” argument against the reality of absolute space by appealing to anti-haecceitist doctrines about possible worlds, influenced especially by David Lewis’s counterpart theory. But separated from Lewis’s distinctive views about what possible worlds are, it is difficult to understand what those doctrines really amount to, and why they are relevant t...

Metzinger’s claim that there are no such things as selves has given rise to a lot of discussions. By examining the notion of self used by Metzinger, I want to clarify what he means when saying that nobody ever was or had a self. Furthermore, I want to examine if there could be a notion of ‘self’ which is compatible with the SelfModel Theory of Subjectivity (SMT). I will argue that there is a no...

The paper argues that, as far as logic and abstract metaphysics go, the claim that composition is identity could be true, despite wellmotivated arguments against the coherence of the claim. The key to answering the arguments is to reject a principle of universal substitutivity of “identical” plural expressions while retaining Leibniz’ Law, that identicals have the same properties, relations, an...

The chance of a physical event is the objective, single-case probability that it will occur. In probabilistic physical theories like quantum mechanics, the chances of physical events play the formal role that the values of physical quantities play in classical (deterministic) physics, and there is a temptation to regard them on the model of the latter as describing intrinsic properties of the s...

This paper presents a model of stochastic growth in which the probability of adverse shocks to production is inversely related to the aggregate stock of capital per capita. Postulating this endogenous relationship, justified by empirical evidence, the model yields long-run predictions consistent with the recent findings of cross-country club convergence and intra-distribution mobility.

in this paper, iron ore sample from the chadormalu was investigated to determine some comminution properties. chadormalu deposit is one of the largest iron ore mine in iran, which is located in yazd province. the representative ore sample contained 57%fe, 0.9%p and 0.17%s. the sample was crushed; afterward, it was ground in various grinding times according to the bond ball mill approach to spec...
