Imperfect Cognitions

This post is by Phil Gerrans and Jeanette Kennett . It is a reply to the post we published on Tuesday on Metaethics and Mental Time Travel . In Metaethics and Mental Time Travel , Fileva and Tresan (F&T) fairly and accurately reconstructed (improved?) and intricately dissected our paper. We cannot follow every twist and turn in a short blog post so concentrate on the key issue. They partially agree with us that semantic knowledge detached from diachronic self-awareness is insufficient for moral agency but disagree (i) whether that awareness needs to be "richly experiential" and (ii) the nature of diachronic deficits in the cases we discuss (see their discussion of these cases which is deeper than ours). As they say, Representations with past- or future-oriented, autobiographical content, crucially, awareness of one’s past actions or future options as consistent or inconsistent with one’s principles do seem necessary : but MTT involves experiential repres...

We are Iskra Fileva and Jonathan Tresan . Both of us teach philosophy, at the University of Colorado, Boulder and at the University of Rochester, respectively.

When we make moral judgments, we often experientially project ourselves into the past or the possible futures, a capacity dubbed “mental time travel” (MTT). For instance, in judging whether her mom was wrong to keep her away from her dad after the parents divorced, Sally may try to recall what it was like to be her father’s daughter. Was it a good experience or a bad one? Was the mother rightly protective or just trying to spite the dad? Sally’s evaluation will likely be informed not just by propositional memories (e.g., “My father was born in June”) but by richly detailed and vivid fi...
