Modern neuroscience has mapped the brain with extraordinary precision, revealing the mechanisms behind perception, memory, and behaviour. Yet for all this progress, it has failed to locate the one thing we most intuitively know to exist: the self. Nowhere in the brain do we find the felt presence of the person—the inner “I” to whom all experience appears.

This absence signals not the end of the mind/body problem, but its return in a new form. A more meaningful way to understand this divide is not as mind versus body, but as spirit versus matter—subjective versus objective reality.
The objective world is shared, measurable, and increasingly illuminated by science. Its truths are consistent and verifiable, forming the basis of our collective understanding.

But this clarity has come at a cost.

In focusing so intensely on the objective, modern thought has often neglected the subjective realm of spirit —the inner domain where meaning, identity, and depth reside.

At the heart of this subjective realm lies the unconscious. Far from being a mere repository of forgotten thoughts, the unconscious can be understood as a living connection to the soul. It is the place where symbols arise, where myth speaks, and where deeper patterns of existence take form. Through dreams, intuition, and imagination, it opens onto something beyond the individual—what many traditions have called the divine or the supernatural.

This inner world is not uniform. It varies from person to person, often remaining hidden, even from ourselves. Yet it is precisely this variability that allows us to encounter meaning in different ways. It shapes what we resonate with in symbolism, spirituality, and depth psychology. It is through the unconscious that we engage with the sacred—not as abstract belief, but as lived experience.
To reduce all of this to neural activity is to overlook the very dimension that gives life its depth. The subjective is not a byproduct of the brain; it is the field in which the sense of self, soul, and transcendence emerges.

To acknowledge a spirit/matter duality is not to reject science, but to place it within a broader context. Science excels at revealing the structure and causes of the objective world, but the ream of spirit and the subjective lies beyond the quantifiable and reproducible empirical truths of the scientific method.

The challenge, then, is not to collapse one into the other, but to hold them in tension. To recognize that the measurable and the meaningful, the external and the internal, the material and the spiritual, are complementary aspects of a more complete understanding of reality.

Science has brought unprecedented clarity to the material world. But to understand the human being fully, we must also turn inward—toward the unconscious, where subjectivity becomes a gateway to spirit, and where the boundaries between self, soul, and the divine begin to dissolve.
