Abstract
The disagreement between André Gombay and Storrs McCall can be summed up in terms of the distinction between liberty of spontaneity and liberty of indifference. This distinction is actually used by Professor McCall in his paper. Thus, it would seem that both speakers agree that a person acting under duress cannot exercise liberty of spontaneity—he does not act according to his wishes. However, Gombay also claims, at least according to McCall, that liberty of indifference is also lacking in cases of duress—persons under duress have no other choice than to obey when threatened. McCall takes an opposite view. He thinks that the only genuine cases of compulsion belong either to various types of physical coercion or to a certain number of pathologies of the mind.
