Abstract

On one possible view of practical reason, that capacity is subject to a standard of correctness determined by independently obtaining facts. This view has recently come under attack, notably in Jeremy Fix’s ‘Intellectual Isolation’. The relevant view, he claims, treats practical reason as a species of theoretical reason and is unable to account for the role that practical reason plays in rational agency. His case relies, however, on a certain conception of theoretical reason: a contemplative conception according to which theoretical reason is practically inert. By embracing that conception, he is led to suppose that exercises of a capacity with an external standard of correctness could not, by themselves, move a subject to act. But the contemplative conception is hardly compulsory. A view according to which practical reason is subject to an external standard need not take the shape, nor involve the corollaries, that Fix, and others, assume it must. Or so I argue.
