Should a leader strive to be loved or
feared This question, famously posed by Machiavelli, lies at the heart of
Joseph Nye’s new book. Mr. Nye, a former dean of the Kennedy School of
Government at Harvard and one-time chairman of America’s National Intelligence
Council, is best known for promoting the idea of “soft power”, based on
persuasion and influence, as a counterpoint to "hard power" , based on coercion
(强迫) and force.
Having analyzed the use of soft and hard power
in politics and diplomacy in his previous books, Mr. Nye has now turned his
attention to the relationship between power and leadership, in both the
political and business spheres. Machiavelli, he notes, concluded that "one ought
to be both feared and loved, but as it is difficult for the two to go together,
it is much safer to be feared than loved." In short, hard power is preferable to
soft power. But modern leadership theorists have come to the opposite
conclusion.
The context of leadership is changing, they observe,
and the historical emphasis on hard power is becoming outdated. In modern
companies and democracies, power is increasingly diffused and traditional
hierarchies (等级制) are being undermined, making soft power ever more important.
But that does not mean coercion should now take a back seat to persuasion, Mr.
Nye argues. Instead, he advocates a synthesis of these two views. The conclusion
of The Powers to Lead, his survey of the theory of leadership, is that a
combination of hard and soft power, which he calls "smart power”, is the best
approach.
The dominant theoretical model of leadership at the
moment is, apparently, the “transformational leadership pattern”. Anyone
allergic (反感) to management term will already be running for the exit, but Mr.
Nye has performed a valuable service in rounding up and summarizing the various
academic studies and theories of leadership into a single, slim volume. He
examines different approaches to leadership, the morality of leadership and how
the wider context can determine the effectiveness of a particular leader. There
are plenty of anecdotes and examples, both historical and contemporary,
political and corporate.
Alas, leadership is a slippery subject,
and as he depicts various theories, even Mr. Nye never quite nails the jelly to
the wall. He is at his most interesting when discussing the moral aspects of
leadership—in particular, the question of whether it is sometimes necessary for
good leaders to lie—and he provides a helpful 12-point summary of his
conclusions. A recurring theme is that as circumstances change, different sorts
of leaders are required; a leader who thrives in one environment may struggle in
another, and vice versa. Ultimately that is just a fancy way of saying that
leadership offers no easy answers. |
