Comment #405 by Nicholas Mertes on

Can we state a similar proposition in the "other direction?" In particular, let be an -category. Can we endow with the structure of a locally Kan simplicial category such that the -category is isomorphic (or perhaps only equivalent) to ? This would mean that we could use a simplicial structure on to "put back" the information lost by passing from to .
