Spirituality as a Dimension of Knowledge Between Reason and Revelation

This study proposes a reconceptualization of knowledge as a multimodal phenomenon, in which spirituality functions as an epistemic dimension that cannot be reduced to demonstrative logic or empirical observation. The central argument is that reason and revelation are not mutually exclusive, but operate synergistically in distinct regimes of truth: reason provides criteria of coherence, universality, and public justification, while revelation functions as an opening to ultimate meaning, corresponding to an experience of transcendence mediated by traditions, symbols, and practices. Through an integrative methodology—which includes frameworks from classical and contemporary epistemology, hermeneutics, phenomenology, religious studies, as well as case studies—we show that "knowing" in the spiritual horizon presupposes a grammar of intellectual virtues, an interpretive exercise, and historical verification through fruition in personal and community life. The conclusion supports the possibility of an expanded rationality, capable of including revealed truths without abdicating the demands of criticism, prudence, and interdisciplinary dialogue.
