Those who care for the future of the human race may well ponder this advice. "If long-cherished ideals and time-honoured institutions, if certain social assumptions and religious formulae have ceased to promote the welfare of the generality of mankind, if they no longer minister to the needs of a continually evolving humanity, let them be swept away and relegated to the limbo of obsolescent and forgotten doctrines. Why should these, in a world subject to the immutable law of change and decay, be exempt from the deterioration that must needs overtake every human institution? For legal standards, political and economic theories are solely designed to safeguard the interests of humanity as a whole, and not humanity to be crucified for the preservation of the integrity of any particular law or doctrine."
