From Plato and the Qur’an to mysticism and neuroscience, this article traces how reason, experience, and culture shape our deepest questions about existence
Shabeer Ahmad Lone
The Qur’an calls humans to recognize ultimate reality through reflection on the cosmos and the self: “We will show them Our signs in the horizons and within themselves until it becomes clear to them that it is the Truth (al-Ḥaqq)” (41:53). Nature and existence are signs (āyāt) inviting contemplation, as “in the creation of the heavens and the earth and the alternation of night and day are signs for people of understanding” (3:190–191), and certainty arises from inward reflection: “on the earth are signs for those of certainty, and within yourselves—will you not then see?” (51:20–21), for “it is not the eyes that are blind, but the hearts within the chests” (22:46). In a letter written in June 1865 to his sister Elisabeth Nietzsche, Nietzsche wrote:
“Here the ways of men divide: if you wish to strive for peace of soul and happiness, then believe; if you wish to be a disciple of truth, then inquire.”
The inquiry into God, ultimate reality, and the nature of consciousness is among humanity’s most enduring and profound intellectual and existential pursuits. It transcends narrow disciplinary boundaries, weaving together philosophy, theology, mysticism, science, ethics, psychology, sociology, and culture, while continually reshaping itself in response to historical, social, and technological transformations. Across Western thought, from Plato’s Forms and Aristotle’s Unmoved Mover to Aquinas’ five ways, reason has long sought to articulate the necessary and intelligible foundations of reality. Yet modern philosophy, from Hume’s critique of analogical inference to Kant’s insistence on the limits of speculative reason, demonstrates the persistent tension between rational justification and epistemic humility.
Existential and process-oriented thinkers such as Kierkegaard and Tillich redirected attention toward subjective engagement, personal commitment, and the ontological grounding of being, highlighting the intimate connection between ethical life and apprehension of the divine. In Eastern traditions, Advaita Vedanta’s non-dual Brahman, Dvaita Vedanta’s theistic dualism, Madhyamaka Buddhism’s emptiness, Yogācāra’s consciousness-centred ontology, and Daoist emphasis on harmony and ineffability collectively illustrate that ultimate reality is apprehended not solely through rational argument but through lived, experiential insight. Across these traditions, mystical experience-from Meister Eckhart and Ibn Arabi to Ramana Maharshi and Patanjali – offers a window into the transformative potential of direct encounter with the ultimate, while cognitive science, psychology, and sociology illuminate the human mechanisms, social functions, and cultural mediations of religious experience. Ethics, politics, language, narrative, and the arts further expand the horizon, demonstrating that God is not merely an abstract object of metaphysical speculation but a dynamic, relational, and socially relevant concept that continues to shape human life, morality, and collective aspiration.
Eastern philosophical traditions present a distinct, often non-dual, orientation toward ultimate reality. Advaita Vedanta, articulated by Śaṅkara, conceives Brahman as non-dual, ineffable, and the substrate of all existence, apprehensible primarily through direct experiential realisation rather than discursive reasoning. By contrast, Dvaita Vedanta, developed by Madhva, maintains a dualistic framework, preserving a clear distinction between God and the individual soul. Buddhist philosophy, particularly Nāgārjuna’s Madhyamaka, challenges inherent existence itself, emphasising dependent origination and the emptiness of all phenomena, including conceptualisations of divinity. Yogācāra places consciousness at the centre of metaphysical inquiry, suggesting that the perception and construction of reality are inseparable from mental processes. Daoist thought, exemplified in the Dao De Jing, prioritises harmony with the ineffable Dao, encouraging non-conceptual engagement and alignment with natural processes.
Within these Eastern traditions, internal debates flourish: some scholars, such as Anantanand Rambachan, suggest parallels between Brahman and Western notions of God, whereas others highlight fundamental differences, stressing impersonal non-duality and the dissolution of the subject-object divide. These debates reveal that comparative analysis must account not only for East-West differences but also for the multiplicity of perspectives within each tradition.
Islamic philosophy offers a powerful integration of reason, revelation, and spiritual insight. Al-Kindi, Al-Farabi, and Ibn Sina articulated divine unity through rigorous metaphysics, culminating in the concept of the Necessary Being. Al-Ghazali emphasised the limits of reason without rejecting it, while Ibn Rushd affirmed the harmony of philosophy and revelation. This synthesis finds its deepest expression in Ibn Arabi’s wahdat al-wujūd and Mulla Sadra’s dynamic ontology of being, uniting metaphysical rigour, ethical responsibility, and transformative experience.
Abrahamic texts consistently invite sincere reflection on God, creation, and self: “Do they not reflect upon themselves?” (Qur’an 30:8) and “We will show them Our signs in the horizons and within themselves until it becomes clear to them that it is the Truth (al-Ḥaqq)” (41:53), while valuing knowledge and contemplation (“Say, ‘Are those who know equal to those who do not know?’” 39:9). They also illustrate that questioning is part of faith: Job grapples with God’s purpose (Job 3:11–23; 7:17–18), the Psalms voice lament and doubt (“How long, O Lord? Will you forget me forever?” 13:1), and Jesus affirms inquiry alongside belief (“Blessed are those who have not seen and yet have believed” John 20:29). Such texts show that thoughtful questioning and contemplation are paths toward understanding the ultimate, while mockery or arrogant denial is cautioned against. The general thrust of each – invitation to reflection and contemplation, honest questioning, and valuing belief alongside inquiry – is present in the scriptures.
Abrahamic traditions portray God as transcendent yet intimately moral, where knowing God requires justice, love, humility, and ethical action.
Mystical experience transcends discursive thought and doctrinal adherence, revealing dimensions of human consciousness that are difficult to articulate yet universally compelling. Christian mystics, such as Meister Eckhart, describe union with God as a radical dissolution of the subject-object distinction, while Sufi mystics like Ibn Arabi articulate the concept of wahdat al-wujūd, the unity of existence in which divine and created reality are inseparable. Eastern mystics, including Ramana Maharshi and Patanjali, describe the realisation of the Self as non-different from ultimate reality, emphasising insight over conceptual reasoning. William James regards mystical experiences as psychologically authentic and transformative, yet epistemologically complex, raising the perennial debate between cultural particularism and universality in religious experience. Phenomenology, drawing on Husserl and Merleau-Ponty, elucidates the embodied, pre-reflective dimensions of consciousness, underscoring the intimate interplay between perception, awareness, and the apprehension of transcendent realities.
Scientific inquiry adds methodological clarity while also imposing constraints on metaphysical speculation. Early modern thinkers, such as Newton, interpreted natural laws as indicative of divine order, but evolutionary biology, cosmology, and quantum mechanics problematize traditional teleological explanations. Cognitive science and neuroscience of religion examine the neural correlates of mystical and religious experience, exploring how brain structures, evolutionary pressures, and psychological mechanisms shape perceptions of the divine. This generates debate about whether religious experience can be fully explained by neurobiology, or whether such explanations risk reducing profoundly existential phenomena to mechanistic accounts. Philosophy of science, from Popper to Kuhn, further clarifies that empirical models are provisional, confined to their paradigms, and cannot exhaustively address ultimate questions of meaning, purpose, or morality.
In the 20th and 21st centuries, thinkers from science and philosophy have illuminated humanity’s place in the cosmos. Julian Huxley (Man Stands Alone) emphasised human autonomy, showing that meaning can arise beyond traditional frameworks while exposing existential isolation. Cressy Morrison (Man Does Not Stand Alone) saw the universe’s intricate order as pointing to a larger purpose, and James Jeans (The Mysterious Universe) highlighted a cosmos whose mathematical coherence invites reflection on mind and matter. Bertrand Russell (Human Knowledge; Religion and Science) stressed the provisional nature of knowledge and the need for ethical reflection alongside scepticism. Together, they reveal a spectrum from human independence to cosmic contingency, keeping the search for ultimate meaning both rigorous and relevant.
Historically, human conceptions of God have evolved in response to moral, philosophical, and social forces. Karen Armstrong (A History of God) traces the shift from polytheism to monotheism, showing a God whose justice, compassion, and authority were continually debated and reinterpreted. This underscores that engagement with ultimate reality is dynamic and multidimensional—ethical, scientific, historical, and reflective—shaping understanding, responsibility, and the human quest for purpose.
Sociological and psychological dimensions illuminate how beliefs in God shape and are shaped by social structures and human cognition. Freud interpreted God as a projection of unconscious desire, while Jung analysed archetypal manifestations of divinity within the collective unconscious. Durkheim highlighted religion’s social function in maintaining cohesion and moral order. Feminist and intersectional perspectives critique patriarchal and Eurocentric conceptions of God, while indigenous and marginalised voices reveal alternative theologies and ontologies. Charles Taylor emphasises that social and psychological explanations complement philosophical and theological inquiry, underscoring that belief is simultaneously personal, cultural, and historical.
Ethics, politics, and applied moral reasoning intersect with divine discourse in profound ways. Western divine-command theories confront dilemmas regarding the grounding of moral goodness, while secular, Buddhist, Confucian, and other frameworks derive ethics from human flourishing, compassion, and relational harmony. Political theology and history demonstrate how conceptions of God have informed governance, law, and social order, from divine-right monarchies to liberation theology and contemporary debates over secularism. Science, philosophy, and theology converge in applied concerns such as bioethics, AI ethics, and environmental stewardship, illustrating that metaphysical beliefs about the ultimate have practical consequences.
Language, semiotics, narrative, and artistic expression mediate human engagement with God. Wittgenstein’s notion of religious “language games” highlights that meaning is practice-dependent, while hermeneutic theorists such as Gadamer and Ricoeur explore how texts, symbols, and rituals frame understanding. Literature, music, and art offer experiential access to the divine, supplementing conceptual reflection and expanding cultural resonance. These dimensions underscore the persistent challenge of articulating ultimate reality while preserving depth, subtlety, and transformative potential.
Taken together, the multifaceted discourse on God, consciousness, and ultimate reality reveals a continuously unfolding horizon, one that integrates reason, experience, culture, ethics, and social engagement. Western traditions contribute analytic rigour, systematic metaphysics, and moral frameworks, while Eastern perspectives foreground non-duality, experiential realisation, and awareness of the limits of conceptual thought.
Mysticism across cultures underscores the transformative potential of direct encounter with the ultimate, even as scientific, psychological, and sociological analyses provide complementary insights into human cognition, behaviour, and social structures. Feminist, intersectional, and global perspectives enrich this inquiry, ensuring that questions of divinity, morality, and meaning remain inclusive and socially relevant. Art, literature, ritual, and language articulate and extend human engagement with the divine, cultivating imagination, reflection, and ethical sensibilities.
God, as a concept and horizon, thus functions not as a closed object of debate but as an ever-evolving, multidimensional axis around which human inquiry, aspiration, and collective flourishing revolve. It is at once timeless and timely, inviting each generation to confront the deepest questions of reality, consciousness, morality, and purpose with insight, humility, and transformative vision.
