Meta-ethics Section 4 Internalism, Externalism and Practicality
Internalism • Moral considerations necessarily either motivate one to act in line with moral judgements, or provide reasons for such action.
Externalism • (Denies the above.) The relation of moral considerations to motivation or to reasons for action is contingent.
Practicality • The practicality of moral language consists in its capacity to motivate or provide reasons for action.
Internalism & Realism • Internalism is often argued to conflict with realism, since factual language is (often) held to lack the practicality that characterizes moral language.
Agent internalism: moral considerations necessarily motivate agents. Appraiser internalism: holding moral beliefs necessarily motivates those holding these beliefs. Internalism about Motivation
Problems • Internalism about the relation of moral language to motivation is misguided, whether it concerns agents or appraisers. • Unacceptable implications.
Internalism about Reasons for Action • Moral considerations necessarily supply reasons for action to relevant people.
Problems • Internalism about the relation of moral language to reasons for action is misguided where it concerns explanatory reasons.
J.L. Mackie Anti-realist argument: • can be construed as concerning either motivation or reasons for action in the sense of explanatory reasons, but establishes its conclusion in neither of these forms.
Justificatory Reasons for Action • Internalism about the relation of moral language to reasons for action in the sense of justificatory reasons is plausible, but is compatible with realism and doesn’t support Mackie’s conclusion.
Consider… • the difference between reasons for action in the sense of explanatory reasons & in the sense of justificatory reasons.
Moral Commitments • The extent & limits of the necessary commitment of adherents of moral judgements lies in their having to judge relevant cases (including their own) in line with their judgements.
Realism • Can be reconciled with internalism about the relation of moral language to reasons for action in the sense of justificatory reasons. • Can also explain the practicality of such language.
Conclusion • Realism overcomes the challenge from internalism. • In view of the positive case for realism and its replies to other objections it should be accepted.
