: Reason has reasons of which ‘reason’ knows nothing. It was this essential insight, along with the methodological prioritisation of a phenomenology of cognition and the recognition of the epistemological distinctiveness of judgment, that a young Bernard Lonergan gleaned from his study of John Henry Newman's Grammar of Assent. Given that the ‘later’, post‐Insight (1953) Lonergan enacted a more explicit transposition of his thought into a hermeneutical and existential framework, one might be tempted to assume that this coincided with a drift away from his tutelage under the nineteenth‐century Englishman. Indeed, an examination of the secondary literature detailing their relationship would suggest as much. Yet, in the hope of contributing to the regrettably sparse Newman‐Lonergan scholarship and proposing a modest recalibration therein, I argue that the more existential, hermeneutical, and committed to the philosophical turn to concrete socio‐historical subjectivity Lonergan grew, the more fruit his early Newmanian formation bore. By analysing Newman's proto‐Lonerganian anticipations in the areas of self‐appropriation, conversion, the relationship of subjectivity to objectivity, and the hermeneutical nature of consciousness, I will contend that Newman—a presciently continental mind writing as one untimely born into an analytical milieu—was the wellspring from which Lonergan never ceased to draw.
