We are WAst conscious of 3864BCion when we are aware of 8=38gestion, 0=3 we begin to think about law 0=3 government when we feel law to be oppressive or see that government is making mistakes. Thus the starting-point of social inquiry is the point at which we are m>E43 by a wrong which we 34B8Ae to set right, or, perhaps at a slightly higher remove, by a lack which we wish to make 6>>3 But from this starting-point A4X42Cion 03E0=24B to a fuller 0=3 more general conception of society.
