"life, liberty, property and the pursuit of happiness." What, you hadn't heard about the "property" part? Well, come back in a few decades after the Clemson Institute for the Study of Capitalism has done its job.
I believe the "property" part comes from John Locke (though I think he may have called it "estate" --
Second Treatise on Government) and from Adam Smith, both founders of the liberal tradition. So, the actual original formula of classical liberalism is indeed "life, liberty, property."
Jefferson added the "pursuit of happiness," having, apparently, cribbed it from Dr. Johnson's
Rasselas. In fact, if we go back to the original passage in Johnson, the phrase becomes poignantly ironic in light of the inevitable failures of the "American Dream":
'“Yet what,” said she, “is to be expected from our pursuit of happiness, when we find the state of life to be such that happiness itself is the cause of misery? Why should we endeavour to attain that of which the possession cannot be secured? I shall henceforward fear to yield my heart to excellence, however bright, or to fondness, however tender, lest I should lose again what I have lost in Pekuah.”'
