6、we may judge a man’s ability by three things ：by what he has done （including the impression he has made on others ），by what he himself appears to believe he can do ，by our own dramatic imagination ，based on his immediate personality ，of what he might do． If these do not agree it is prudent to observe him further．(Charles   Horton   Cooley ，Life   and   the   Student)
