Recent developments of molecular theories of nucleation, involving both analysis and simulation are considered. Subtle issues that arise in connection with these theories are analyzed and discussed with an emphasis on exactness. The focus is on three topics. These are (i) mapping of fluctuations simulated in a small cell onto the macrosystem, (ii) kinetics and dynamics of the nucleation rate, and (iii) the "nucleation theorem".
