Conscientia "is nothing other than the application of knowledge to some act" (ST I q. 79 a. 13; fuller treatment in De Veritate q. 17). So conscience is your mind — your mind judging this concrete deed in light of moral first principles. You're not trying to hear a second voice over the din of the first. You're trying to tell one act of the one mind from its counterfeits.
