In this paper, we take a fresh look at three Popperian concepts: riskiness, falsifiability, and truthlikeness of scientific hypotheses or theories. First, we make explicit the dimensions that underlie the notion of riskiness. Secondly, we examine if and how degrees of falsifiability can be defined, and how they are related to various dimensions of the concept of riskiness as well as the experimental context. Thirdly, we consider the relation of riskiness to truthlikeness. Throughout, we pay special attention to probabilistic theories (...) and we offer a tentative, quantitative account of verisimilitude for probabilistic theories. (shrink)

Carl Hoeferʼs “freedom from the inside out” is a compatibilist account of freedom that claims that we can have a robust kind of freedom even if the world is deterministic. The key insight is that determinism belongs in tenseless B-series time in the block universe, not in our everyday notions of the world where time is experienced in a tensed way with a past, a present, and a future, where the past is viewed as fixed and the future as open. (...) The block universe is time symmetric, i.e., determination can go in both temporal direction, and no particular part of the block universe is determined or fixed prior to any other part. Therefore,we do not have to think of deterministic logical relations as placing constraints on our actions in advance. Instead, we are free to view our actions as primary explainers that very partially determine both the future and the past. Since our actions are thought to place constraints on the microscopic past, it will be argued that Hoeferʼs account can question the Consequence Argument, the well-known incompatibilist argument that claims that if the past and the laws are not up to us, the consequences of the past and the laws cannot be up to us either, which includes our present actions. Hence, it will be argued that by rejecting that the past is not up to us, Hoeferʼs account can refute the Consequence Argument, which removes one possible threat to our freedom. (shrink)
