"In many ways, Dahl created the field of modern political science. To be sure, the scholarly study of politics goes back to at least the ancient Greeks. Dahl was no Plato, Aristotle, or Thomas Hobbes, but he added something new to the armchair reflection leavened by illuminating anecdote that had characterized the enterprise for millennia: the systematic use of evidence to evaluate rigorously stated theoretical claims. Generations of Dahl’s successors have developed both theories and empirical methods in multiple directions since he produced his innovative works in the 1950s and 1960s, sometimes in ways that he found less than congenial. Few would deny that they stood on Dahl’s shoulders."
