The paper examines time series properties and efficiency of a securities market where disparately informed traders hold rational expectations and extract signals from the endogenous market price. Two equilibria are calculated, using a method of Sargent to handle the problem of infinite regress. When rational speculation is the sole source of potential trade, the market price reflects all privat...

In this paper, we shall describe and critically evaluate four contemporary theories which attempt to solve the problem of the infinite regress of reasons: BonJour's ‘impure’ coherentism, BonJour's foundationalism, Haack's ‘foundherentism’ and Dancy's pure coherentism. These theories are initially put forward as theories about the justification of our empirical beliefs; however, in fact they als...

This paper is the third and final one in a sequence of three. All three papers emphasize that a proposition can be justified by an infinite regress, on condition that epistemic justification is interpreted probabilistically. The first two papers showed this for one-dimensional chains and for one-dimensional loops of propositions, each proposition being justified probabilistically by its precurs...

According to radical probabilism, all factual claims are merely probabilistic in character. Throughout the centuries this view has been criticized on the grounds that it triggers an infinite regress: if every claim is probabilistic, then the proposition that something is probable is itself only probable, and so on. An endless hierarchy of probabilities seems to emerge and, as a result, the prob...

Quality of a product needs verification. If the product is complex, this verification cannot be done “by hand”, but one needs tools. How then are those tools being checked? Eventually quality comes from a careful specification and design methodology. Warranty is based on a mathematical proof that the design meets its specification. As mathematical proofs become long and complex themselves, we a...

1. There are two ways to consider the eternity of the world: the one focussing on the world’s substance, the other on its motion. The latter sort of consideration is proper to physics and so should be passed over in the present science – even though we will not be able to avoid mentioning it below when we demonstrate that God exists and that there cannot be an infinite regress among efficient c...
