“The distinction between sanity and insanity is narrower than the razor's edge, sharper than a hound's tooth, more agile than a mule deer. It is more elusive than the merest phantom. Perhaps it does not even exist; perhaps it is a phantom.”

Context: Perhaps even more than constituted authority, it is social uniformity and sameness that harass the individual most. His very "uniqueness," "separateness" and "differentiation" make him an alien, not only in his native place, but even in his own home. Often more so than the foreign born who generally falls in with the established.

Context: The tables of criminality for different ages, given in my published treatise, merit at least as much faith as the tables of mortality, and verify themselves within perhaps even narrower limits; so that crime pursues its path with even more constancy than death.... it is still betwixt the ages of twenty-one and twenty-five, that, all things being equal, the greatest number of persons are to be found in that position [of a criminal].
