*θ*is a challenge to the notion of an anthropic landscape. We briefly review the possibility that a suitable axion might arise from an anthropic requirement of dark matter. We then consider an alternative suggestion of Kaloper and Terning that

*θ*might be correlated with the cosmological constant. We note that in a landscape one expects that

*θ*is determined by the expectation...
