An early story punched up to novel length from Blish centered around a hyper-rational exploration of Fortean concepts and human psi-abilities.

Blish's erudition and intelligence is on display here, but the plot and prose alternates between boilerplate pulp, and messy/technical exposition on how psi-abilities might actually work.

I struggled mightily to finish this one. Probably not worth it for anyone except a Blish completionist.
