ABSTRACT
A system is deterministic just in case the state of the system at one time xes the state of the system at all future times. A system is indeterministic just in case it is not deterministic. The question whether systems (or models or the world) are deterministic or indeterministic has concerned philosophers and scientists from the very beginning of philosophical and scienti c thinking and still concerns them today. This article focuses on three recent discussions on determinism in the philosophy of science. First, determinism and predictability will be discussed (Section 2). Then, second, the chapter turns to the topic of determinism, indeterminism, observational equivalence, and randomness (Section 3). Finally, third, there will be a discussion about deterministic probabilities (Section 4). The chapter will end with a conclusion (Section 5).
