Adam Smith and Malthus and Ricardo ! There is something about these three figures to evoke more than ordinary sentiments from us their children in the spirit.
It would be fun too to put some of the great philosophers and political scientists of the past couple centuries into a time machine, have them look at the world today, and see what they think. Imagine Schumpeter, Malthus, Hobbes, Nietzsche, Marx, and more! That would be good fun.
