When we consider the wide, almost unlimited range of the legislative function, and the power and tendency of legislatures to push that function to the extreme, it would seem that some check should be put upon the legislature to prevent its enacting discriminatory laws or otherwise depriving the individual of some accustomed and cherished freedom of action. If it be said that public opinion is sufficient restraint, the answer is that in a democracy, or in a republic with universal suffrage, the efficient public opinion is practically that of the majority of the electorate, and it is an acknowledged truism that the unrestrained majority is even more likely than the few to be oppressive of the individual. The opinion of the many is more variable than that of the few, more likely to be swayed by sympathy, prejudice, and other emotions. Indeed, public opinion sometimes induces legislatures to enact laws which they themselves feel to be unwise and tyrannical. If history and reason show that the happiness of the people as a whole requires certain individual liberties and rights to be left undisturbed and that the safety of the people as a whole does not require the contrary, then in order to secure justice those possessing the powers of government should be restrained from any acts infringing those liberties and rights; for, as already stated, justice consists in the equilibrium between restrictions necessary for the welfare of the whole people without discrimination, and the freedom of the individual to serve his own welfare.
