Montesquieu is among the greatest philosophers of liberalism, but his is what Shklar has called
"a liberalism of fear" (Shklar, Montesquieu, p. 89). According to Montesquieu, political liberty is
"a tranquillity of mind arising from the opinion each person has of his safety" (SL 11.6). Liberty
is not the freedom to do whatever we want: if we have the freedom to harm others, for instance,
others will also have the freedom to harm us, and we will have no confidence in our own safety.
Liberty involves living under laws that protect us from harm while leaving us free to do as much
as possible, and that enable us to feel the greatest possible confidence that if we obey those laws,
the power of the state will not be directed against us.
