Instrumental rationality in the modern era, by reducing the human-world relationship to function, utility, and control, has constrained the moral and meaningful horizons of human life. This article employs a comparative approach to examine Charles Taylor's and Reza Davari Ardakani's critiques of instrumental rationality and asks whether this critique opens the possibility for rethinking religious spirituality and recovering sacred horizons in the contemporary world. The central hypothesis is that despite their fundamental philosophical differences, both thinkers converge on a crucial point: the modern subject, when relying exclusively on instrumental reason, faces a crisis of meaning, the weakening of normative horizons, and a rupture with transcendence. Taylor, in works such as Sources of the Self, The Ethics of Authenticity, and A Secular Age, demonstrates that secularization does not necessarily entail the elimination of religion, but rather constitutes a transformation in the conditions of belief and unbelief. Davari Ardakani, through his critique of developmentism, technique, and the dominance of scientism, characterizes the crisis of modernity as a crisis in the human relationship with truth, culture, and thought. The article concludes that religious spirituality, in light of these two critiques, should not be understood as a simplistic return to tradition, but rather as a critical re-examination of the relationship between religion, reason, history, and the lifeworld.
