The Routledge Handbook of Classical Liberalism is now available and Open Access. My contribution to the volume was on “The Future of Liberalism.” I actually found writing this piece very difficult for a variety of reasons and the historical context at the time of the writing. My bottom line is that goal of liberalism is peace both domestically and internationally, and the only way to achieve that is through toleration and trade. Intolerance and protectionism are the antithesis of liberalism, and without liberalism we don’t achieve peace either at home or abroad. War is the natural state, transitioning from that to a social order of peace and prosperity takes more than technological change — it is grounded instead in a shift in the basic mental model we adopt. Not zero sum, but positive sum thinking. Not conquest and conquer, but trade and social learning. So my call is to cultivate the moral imagination necessary throughout society for the liberal order of “strangers nowhere in this world” and for “perpetual peace” to have a chance. It is ultimately about dignity and respect of individuals, of the sacredness of persons and their projects, of the sanctity of property and contract, and civility and moral sympathy.
