 If the requirements for sufficient maturity and consideration are minimal, then there will be little difference between self-evidence as defined by Ross and (SE). But Ross’s approach would include a “fudge factor” that might be useful. It could, e.g., enable him to avoid purported counterexamples where S understands some self-evident moral proposition, PSE, but we are disinclined to grant that PSE is justified for S either because S suffers from some general cognitive deficiency, e.g., excessive credulity, or the circumstances in which S understands P are problematic for some reason, e.g., S is exhausted or distracted. Ross could simply point out that S lacks mental maturity or has failed to give PSE sufficient consideration, and thereby avoid having to say that S has a justification for PSE.
