 Duty and Ignorance of Fact

Show Summary Details


Prichard's concern here is whether a person's obligation depends either on features of his or her situation (and therefore on the effect of his or her action) or on features of his or her thoughts about that situation. Related to this contrast between the objective view and the subjective view is the issue of whether an obligation is an obligation to do some action. To the latter issue, Prichard responds that an obligation is not an obligation to do something, but an obligation to set ourselves to do something; as a consequence, it is necessary to modify the terms of Prichard's primary concern. This modification diminishes the force of the objective view and does nothing to eliminate the central difficulty in the subjective view, namely, that the obligation to do some action is said to depend not on the character that the action would have, but on our belief that it would have that character. The belief that some general character picks out obligations derives from the mistaken habit of regarding the terms ‘right’ and ‘wrong’ as equivalent to ‘ought’ and ‘ought not’. Having highlighted this mistake, Prichard holds that in instances where we have considered the circumstances fully, our thoughts about the situation decide whether we ought to perform a given activity.
