I discuss QBism, or quantum bayesianism, in the light of several of Christopher Fuchs' papers. Quantum Bayesianism is the extension of the Bayesian interpretation of probability -- one of many subjective views of the nature of probability -- to quantum mechanics. In essence, the view is that the wave function is your personal assessment of likelihoods of experiments and that the results of experiments are your personal experiences, and that the use of these experiments is to update your view of the world.

This is a great discussion, from top to bottom! The subsequent ones are as well. Perhaps one day this series will be reanimated :)
