The five senses of the body and the five senses of the soul in Aristotle, St. John Damascene, Evagrius Ponticus, St. John Climacus, and St. Maximus the Confessor
The prophet Jeremiah writes a verse the desert fathers never forgot: death has come up into our windows (Jeremiah 9:21). Not „through the doors” — through the windows, those openings through which light enters unbidden, and through which, just as naturally, darkness can enter too. The body has five such windows. Philosophy counted them first. The Holy Fathers examined them more deeply, showing that the same openings can be either a gate of death or a gate of light, depending on who keeps watch over them. And the modern mind, unknowingly, confirms today, in other words, the same old doors.
Aristotle: the gate to knowledge
For Aristotle, sensation (aisthesis) is not a mere appendage of the body but the very beginning of knowledge. Man desires to know by nature, and the clearest sign of this desire is the delight he takes even in the useless exercise of the senses, sight above all, which Aristotle ranks first among them because it yields the greatest wealth of distinctions. In On the Soul, Aristotle explains that sense is that which is capable of receiving the form of the sensible object without its matter — the eye receives the image, not the substance, of the stone. Each sense has its own proper object (color for sight, sound for hearing), and beyond the five there is a „common sense” that gathers the scattered data into a single perception of the whole thing — we do not separately see a yellow patch and separately feel a roundness; we perceive a lemon.
It is a sober, empirical psychology, free of suspicion toward the body. Aristotle does not despise the senses, as Plato does, for whom they are mere shadows on the cave wall, deceptive witnesses to be transcended by pure reason. For Aristotle, sense is the first and most trustworthy step toward truth — yet he too observes, with clarity, that sense alone does not judge: it receives, but does not discern good from evil. That remains the work of a higher power. Even Aristotle leaves open a question that only the Holy Fathers would carry to its end: who governs the sense, if not the sense itself?
St. John Damascene: the body’s windows in the mind’s service
St. John Damascene, in his Exposition of the Orthodox Faith, takes over almost the entire Aristotelian scheme of the senses — filtered through Nemesius of Emesa, who had already Christianized Greek physiology and psychology — but sets it within a new order. The five senses are not an end in themselves but tools given to man by the Creator for a specific task: the governing and naming of the world, as Adam named the animals (Genesis 2:19-20), not servitude to them. Damascene’s physiological description of the eye, ear, smell, taste, and touch is almost identical to Aristotle’s — but it is immediately followed by a chapter on the rational mind (nous), on will, on imagination and memory, showing plainly where the thread is meant to lead: not to sense as master, but to mind as the sense’s master, and through mind, to God.
Here lies the decisive difference from pagan philosophy: for Damascene, man bears the image of God precisely through his rational part, and the senses are good servants as long as they obey their true master. When the order is overturned — when mind serves sense instead of guiding it — the whole man is overturned. The windows remain the same; only the one who dwells in the house changes.
Evagrius Ponticus: the thief at the window
If Damascene describes the architecture, Evagrius describes the siege. In the Praktikos and the treatise On Thoughts, he shows with almost clinical precision how the passions (pathē) are not born from nothing but attach themselves to the soul through the gate of the senses: an image seen, a scent remembered, a touch allowed without watchfulness — and the thought (logismos) finds its foothold. Demons, Evagrius says, cannot touch the mind directly; they „paint” images upon the senses, especially the two bound to imagination — sight and hearing — and wait for the inattentive soul to receive within what should have been stopped at the threshold.
From this comes the Evagrian command of nepsis — watchfulness that guards the gates of the heart, examining every thought at the entrance, as a customs officer examines goods at the border before they are allowed into the city. It is not the sense that is guilty — Evagrius preaches no contempt for the body — but its lack of oversight. Yet Evagrius, following Origen, goes further still: the mind purified of passions acquires, he says, senses of its own — a sight that no longer needs the bodily eye to behold the formless light of God in prayer, the image of the sapphire sky that Moses sees (Exodus 24:10) being the figure of this vision unknown to the ordinary senses. Thus in Evagrius, the bodily window may be closed for a time — not by amputation, but by stillness — so that another, more inward sight may open.
St. John Climacus: the keeper at the gate
The Ladder of St. John continues from exactly this point — not as theory, but as daily discipline. Almost every step of the Ladder touches, directly or indirectly, on guarding the senses: silence of the tongue as a gate to dispassion, the wandering eye as herald of passion before the passion has reached the heart, an unwatched touch as a spark that can ignite what fasting and vigil had barely extinguished. St. John Climacus never treats the senses apart from the monk’s daily labor — for him, the monk is like a fisherman watching his net: if one mesh tears, all the fish caught with such toil may escape through that single unnoticed hole.
The Lord teaches the same in the Gospel: the light of the body is the eye; if therefore thine eye be single, thy whole body shall be full of light (Matthew 6:22). Climacus reads this saying not as an empty metaphor but as an exact spiritual law: the clean window lights the whole house; the dirty window darkens the whole house, however clean the other rooms may be. This is why he places discernment (diakrisis) above every other virtue, even above severe fasting or long vigil — for without discernment, not even asceticism itself knows whom it serves.
St. Maximus the Confessor: the transfigured window
St. Maximus provides the key that binds all of the above into one coherent figure. He teaches that every natural power of man — and so the senses too — can work in three ways: according to nature (kata physin), against nature (para physin), or above nature (hyper physin). The same eye that, used according to nature, contemplates the Creator’s wisdom in the beauty of creation (a form of silent prayer St. Maximus calls natural contemplation) can also be used against nature, enslaved to self-love (philautia), becoming the instrument of lust; but it can equally be raised above nature, by grace, as happened on the mountain of the Transfiguration, when the disciples’ bodily eyes saw a light that sense, left to its natural powers alone, could never have contained.
Here the doctrine of the „spiritual senses,” which Origen had sketched earlier by reading Scripture as a map of the soul’s five senses, finds its fulfillment: a sight that beholds the glory of God, a hearing that listens to the voice of the Word, a smell that perceives the sweet savor of Christ (2 Corinthians 2:15), a taste that tastes and sees that the Lord is good (Psalm 34:8), a touch that handles the Word of life with its own hands (1 John 1:1). In St. Maximus, these „senses” are not added on top of the five as a second row of windows; they are the same five senses, transfigured — showing that the body is not the spirit’s enemy but its natural vessel, when rightly ordered.
The psychological echo: perception is never empty
What the Fathers said in the language of the spirit, modern psychology confirms structurally, though without the word grace. Perception research has long shown that sense never receives raw, „empty” data — perception is always already filtered by attention, expectation, and prior emotional state; the figure-ground phenomenon of Gestalt psychology, and the so-called „cocktail party effect” (the ability to hear one’s own name spoken across a noisy room without consciously tracking anything) show that the mind chooses, before sensation is even complete, what deserves to be sensed. And habituation, together with dopaminergic reward circuits, describes precisely what Evagrius called the coarsening of sense under passion: repeating the same stimulus raises the threshold needed for the same pleasure, binding attention ever more tightly — a secular description of what Scripture had already named, centuries before, as senses trained by practice to discern good and evil (Hebrews 5:14), either toward good, or, if the training is corrupted, toward evil.
The philosophical echo: neither contempt nor blind trust
Between Platonic contempt for the senses, as shadows to be abandoned, and naive empiricist trust that sense alone gives the whole truth, the Fathers chose a third path, harder than either: the sense is neither enemy nor master, but a tool whose worth lies in its use. This is exactly the structure Aristotle himself gave to virtue — not in the faculty, but in its right exercise. Something of this same intuition resurfaces, centuries later, in the phenomenology of Merleau-Ponty, for whom we do not „have” a body as a foreign instrument but are our body, and perception is the primary contact with the world, prior to all reflection — an unknowing philosophical echo of the same patristic insight: sense is not opposed to spirit but its natural vehicle, when spirit governs it, and its grave, when it does not.
The window remains the same
Jeremiah did not say the windows must be walled up. He said only that death had climbed up into them. The same five openings through which forgetfulness of God enters, unwatched, are the very ones through which, watched over, the unfading Light can enter (Psalm 27:1; John 1:5,9). The body is not asked to stop seeing, hearing, or feeling — only for the mind to return to its place, a wakeful keeper at the gate, examining every guest before letting it in. Then the window through which death once entered becomes, without changing its shape, the window through which the Lord enters, quietly.
