  There is also a problem with premise (1), concerning the GD conception of justification. While it is true that some philosophers who have accepted internalism, of either the accessibility or mentalist forms, have also accepted this GD conception, they need not do so. Indeed, some leading internalists explicitly reject the GD conception and any deontological concept that is proposed as an analysis of the concept of justification, and yet this fact has no effect on their one important form of internalism, namely mentalism (Conee and Feldman 2001). These comments reinforce the comments made earlier to the effect that the deontological concept of justification is really independent of accessibility internalism and mentalism.
