In “How to Choose?,” Michael Schulson describes situations in which the rational thing to do might be to choose without having reasons for your choise. “When your reasons are worse than useless, sometimes the most rational choice is a random stab in the dark.”

Ought implies can … or not
In “The Data against Kant,” Vlad Chituc discusses psychological research challenging Kant’s principle that ought implies can. This is the principle that “it would be absurd to suggest that we should do what we couldn’t possibly do.” The research shows that there are common situations in which nonphilosophers do think it makes sense to say someone ought to do something that it is impossible for them to do it. In these situations “ought” has more to do with “blame” than with “can.” This in turn raises questions about “experimental philosophy” and the role the intuitions of nonphilosophers ought to play in philosophical analysis. Can we draw conclusions about what we ought to think from data about what some people actually think?
Free will and neuroscience
Which happens first … a conscious decision to do something or the brain activity associated with doing it? Thanks to experiments Benjamin Libet conducted in the 1980s, it seemed that “the timing of … conscious decisions was consistently preceded by several hundred milliseconds of background preparatory brain activity.” It seemed, that is, that our brains had already acted to carry out what we only later consciously decided to do. But in “Neuroscience and Free Will Are Rethinking Their Divorce,” Christian Jarrett says that may be changing. As researcher Dr. John-Dylan Haynes puts it, neuroscience may actually show that “a person’s decisions are not at the mercy of unconscious and early brain waves.”
Phantom attention
In “How Phantom Limbs Explain Consciousness,” Michael Graziano says that “the brain’s model of the body can tell us a lot about its model of attention.” Just as the brain generates a schema of the body, it generates a scheme of attention. “You know, the feely thing inside me. Consciousness.”
