If you believe that laws forbidding gambling, sale of liquor, sale of contraceptives, requiring definite closing hours, enforcing the Sabbath, or any such, are necessary to the welfare of your community, that is your right and I do not ask you to surrender your beliefs or give up your efforts to put over such laws. But remember that such laws are, at most, a preliminary step in doing away with the evils they indict. Moral evils can never be solved by anything as easy as passing laws alone. If you aid in passing such laws without bothering to follow through by digging in to the involved questions of sociology, economics, and psychology which underlie the causes of the evils you are gunning for, you will not only fail to correct the evils you sought to prohibit but will create a dozen new evils as well.
