 To accommodate this more subtle kind of difference, proponents of the principle of charity might point out that charity does not require complete agreement, but only “substantial” agreement or agreement on “ultimate” or “fundamental” disagreement. A further question that will pressed against this position is how much agreement is sufficient for identification of others’ beliefs as being about the same subject matter as ours. We do attribute to others error and simple difference (without judging that someone is in error) of belief about the same subject matter. We can attribute error to others if we believe them to be in circumstances that encourage error, and we identify such types of circumstance from past experience of discovering ourselves to be in error. Furthermore, we attribute simple difference of belief when we recognize that there is a range of reasonable interpretations or weightings to be given to evidence.
