Abstract
Based on his philosophical-mystical foundations regarding love, The Grand Sheikh considered love to be flowing and prevalent in all aspects of existence, and examined it in seven chapters of various levels of existence. He analyzed love in animal souls, love in beautiful forms, love in divine souls, and finally love in divine nature, which is the highest and most perfect type of love. In his philosophical-mystical view, love was absolute good, as he believed that good is in itself desirable, popular and beloved. He defined every movement in the world of possibility towards perfection as love; and considered all such movements to be the result of love incarnated in every living being—how he defines love in “A Treatise on Love” (Risālah fī al-'Ishq). As a doctor, he mentioned love as a disease that presents with symptoms, and that comes with a cure. In the law, love is recognized as a disease, as the soul and body affect each other. The psychological symptoms of love in the fourth stage, that is, love in the animal soul, manifests in the body of the lover; having observed symptoms such as emaciation, cachexia, dry and sunken eyes, the doctor diagnoses a disease—a disease affected by carnal passions.


Introduction
Love, as one of the most profound and enduring human experiences, has captivated the attention of philosophers, mystics, poets, and physicians throughout history. Its nature, origins, and manifestations have been explored from countless perspectives, yet its essential mystery remains elusive. Among the most remarkable figures to address this phenomenon is Ibn Sīnā (Avicenna, d. 1037), the preeminent philosopher-physician of the Islamic world. Uniquely situated as both a master of philosophical metaphysics and a practitioner of medicine, Ibn Sīnā offers a distinctive dual perspective on love that reflects the depth and breadth of his intellectual vision. In his philosophical and mystical writings, particularly the Risāla fī al-'Ishq (Treatise on Love) and the final sections of the Ishārāt wa al-Tanbīhāt (Remarks and Admonitions), he presents love as a cosmic principle pervading all levels of existence, from the simplest material substances to the Divine Essence itself. In his medical magnum opus, the Qānūn (Canon of Medicine), however, he discusses love as a specific psychological-physical disorder with identifiable symptoms, causes, and treatments.
This apparent duality raises a fundamental question: How could the same thinker who portrays love as the supreme cosmic good and the motive force behind all movement toward perfection also describe it as a form of melancholic obsession requiring medical intervention? Is there a contradiction in Ibn Sīnā's thought, or does his sophisticated philosophical psychology provide the means to reconcile these seemingly disparate perspectives? The present study seeks to address this question by examining Ibn Sīnā's treatment of love across his philosophical and medical writings, demonstrating that far from being contradictory, his two perspectives reflect a coherent and integrated understanding of love as a phenomenon that manifests differently across the ontological hierarchy of existence.
The significance of this investigation lies in its potential to illuminate the deep connections between Ibn Sīnā's philosophical anthropology, his medical theory, and his mystical thought. By examining how love functions at different levels of existence—from inanimate substances through plants, animals, and human beings to the Divine—we can appreciate the systematic unity of his intellectual project and the sophisticated way in which he integrates insights from philosophy, mysticism, and medicine into a comprehensive worldview. This study contributes to the growing body of scholarship on Ibn Sīnā's psychology and his theory of the soul-body relationship, while also offering insights into the broader question of how pre-modern thinkers integrated scientific and philosophical approaches to human experience.

Research Methodology
This research employs a descriptive-comparative method, systematically examining Ibn Sīnā's treatment of love in his philosophical and medical writings. Data were collected through library research, focusing on primary sources including the Risāla fī al-'Ishq, the Ishārāt wa al-Tanbīhāt (particularly the eighth section on love), and the Qānūn fī al-Ṭibb (Book Three, on diseases of the soul). The analysis proceeds through careful textual examination, conceptual clarification, and systematic comparison of Ibn Sīnā's philosophical and medical perspectives.
The descriptive phase involves presenting Ibn Sīnā's seven-fold hierarchy of love as articulated in the Risāla fī al-'Ishq, from the simplest inanimate substances through vegetative souls, animal souls, human souls, and ultimately the Divine Essence. Each level of love is described in terms of its objects, motivations, and characteristics. The medical perspective is then examined through Ibn Sīnā's discussion of love as a disease in the Qānūn, including its definition, symptoms, diagnosis, and treatment. The comparative phase synthesizes these two perspectives, demonstrating how they are reconciled through Ibn Sīnā's theory of the soul-body relationship and his understanding of the graded nature of existence.
The research also engages with relevant secondary literature and commentaries on Ibn Sīnā's thought, including the works of later philosophers such as Mullā Ṣadrā and contemporary scholars, to contextualize the analysis and to assess the broader implications of Ibn Sīnā's views for understanding the relationship between philosophy, mysticism, and medicine in the Islamic intellectual tradition.

Discussion
Love in Ibn Sīnā's Philosophical-Mystical Thought
In Ibn Sīnā's philosophical framework, love is understood as a fundamental cosmic principle that pervades all levels of existence. He begins the Risāla fī al-'Ishq by asserting that the concept of love is self-evident and requires no proof; rather, his task is to demonstrate its presence and operation throughout the hierarchy of being. The treatise proceeds through seven chapters, each corresponding to a different level of existence, from the simplest material substances to the Divine Essence.
Ibn Sīnā's understanding of love is grounded in his metaphysical principles. Following the axiom that "every contingent being is a composite of existence and quiddity," he argues that existence is the source of all good and perfection, while quiddity is the source of limitation and deficiency. Every contingent being, by virtue of its existence, yearns toward good and perfection, and by virtue of its quiddity, recoils from deficiency and imperfection. This innate yearning is what Ibn Sīnā calls "love." It is a natural, instinctive inclination that permeates all of creation and ensures the preservation and continuity of existence.
Love in Inanimate Substances: Ibn Sīnā identifies three types of simple, non-living substances, each possessing its own form of instinctual love. Prime matter (hayūlā) loves form, constantly seeking it to actualize its potential, much like an ugly woman who covers her face to hide her ugliness. Form loves its subject, never separating from it, and accidents love their subjects as well, because without them they would have no existence. Even in the simplest material substances, there is a kind of natural love that ensures their continued existence and proper functioning.
Love in Plants: The vegetative soul possesses three faculties—nutrition, growth, and reproduction—each associated with a specific form of love. The nutritive faculty loves food, seeking it when needed and incorporating it into the organism. The growth faculty loves expansion, striving to develop in three dimensions in proportion to the organism's capacity. The reproductive faculty loves generation, seeking to produce a being similar to itself to ensure the continuity of the species. These loves are natural and instinctual, operating without choice or deliberation.
Love in Animals: The animal soul has faculties that are each characterized by specific natural loves. External senses have natural inclinations toward certain objects and aversions toward others—without these, all sensations would be equal and the animal would be unable to distinguish beneficial from harmful. Internal senses, including imagination and memory, experience love as a sense of ease and pleasure when their objects are present and a yearning when they are absent. The irascible faculty loves victory, revenge, and overcoming enemies, and recoils from humiliation. The concupiscent faculty loves reproduction and the satisfaction of natural desires.
Ibn Sīnā distinguishes between natural and voluntary love in animals. Natural love operates without choice, as in the case of reproduction driven by the reproductive faculty; voluntary love involves choice and deliberation, as when an animal chooses between different goods based on its understanding of what will best preserve its life. The concupiscent faculty in animals serves as a bridge between natural and voluntary love, reflecting God's wisdom in ensuring the continuity of species through a combination of instinctual drive and conscious choice.
Love of Beautiful Forms: At the human level, love of beautiful forms manifests in three progressively more refined ways: embracing, kissing, and sexual union. The third type, sexual union, belongs to the animal aspect of human nature, but when conducted within the bounds of religious law and for the purpose of procreation, it participates in the divine wisdom of preserving the species. The first two types—embracing and kissing—are expressions of the love of beauty itself, rather than of physical desire, and they reflect the natural affinity between souls.
Ibn Sīnā also addresses the relationship between outer beauty and inner character. He cites the Prophet's saying, "Seek your needs from those who have beautiful faces," arguing that a person's external appearance is often a reflection of their inner nature, though this is not always the case, as external circumstances or bad company may obscure an originally good nature. Thus, human love of beautiful forms can serve as a gateway to higher forms of love, provided it is guided by wisdom and law.
Love of Divine Souls: The highest level of love attainable by human souls is the love of God, the Absolute Good. Every soul that perceives the good naturally loves it, and souls—whether human or angelic—love the First Cause because their perfection consists in cognizing intelligibles and in resembling the Absolute Good through knowledge and virtuous action. Angels love the preservation and continuation of the cosmos, and their love is a reflection of the love of the First Cause for creation.
Ibn Sīnā concludes his treatise by establishing that all beings love the Absolute Good by their very nature, and that the Absolute Good, in turn, loves to bestow its goodness upon all beings through its eternal generosity. The existence of all beings is a manifestation of divine love. True love is the delight in the perception of the presence of the Good, while longing (shawq) is the movement toward the completion of that delight. God, as the ultimate object of love, is both lover and beloved, as His essence is the most perfect object of perception and delight.
Love as a Disease in Ibn Sīnā's Medical Thought
In his medical work the Qānūn, Ibn Sīnā presents a strikingly different perspective on love, discussing it as a specific disease that primarily affects young people whose minds become preoccupied with the beauty of another person. He identifies it as a form of melancholic obsession (marad waswāsī) closely resembling melancholia (mālikhūliyā), characterized by the sufferer's persistent absorption in thoughts of the beloved, to the exclusion of all else.
Ibn Sīnā provides a detailed description of the physical symptoms of love-sickness: hollowed, dry eyes that water only when crying; drooping eyelids that suggest a gaze upon something delightful; intermittent breathing with deep sighs; a disheveled appearance; and an irregular pulse that changes when the beloved's name is mentioned or when the beloved appears. The sufferer may fluctuate between intense joy and deep sadness, sometimes laughing one moment and crying the next. The body loses its moisture and becomes dry, thin, and weak—much like a liquid that evaporates under heat.
One of the most remarkable aspects of Ibn Sīnā's medical discussion of love is his method for diagnosing the identity of the beloved. The physician should take the patient's pulse while mentioning various names, observing when the pulse changes; then, with the name of the beloved identified, the physician should mention various cities and regions until the place of the beloved is also discovered. By combining the name and location, the physician can identify the beloved and, if possible, arrange for the patient to be united with them.
Ibn Sīnā provides practical therapeutic advice. Once the patient's humors have been properly balanced and cleansed, the physician should seek to distract the patient's mind through engaging conversations and pleasant activities. The patient should be encouraged to consider the beloved's faults and to hear negative reports about them from old women. If possible, the patient should be encouraged to transfer their affection to another person, provided this can be done lawfully. In more severe cases, where the disease has become deeply entrenched, more aggressive treatments may be required, including those used for melancholia and mania.
A notable limitation of Ibn Sīnā's medical treatment of love is that he provides specific therapeutic recommendations only for men. While he acknowledges that both men and women can suffer from love—the story of Zulaykhā and Joseph serving as a prominent example—he does not offer parallel therapeutic advice for women. This limitation may reflect the social constraints of his time, when women were unable to disclose their feelings publicly due to the shame associated with love, but it remains a significant oversight in an otherwise comprehensive medical account.
Reconciling the Two Perspectives: The Soul-Body Relationship
The apparent contradiction between Ibn Sīnā's philosophical and medical views of love is resolved through his sophisticated understanding of the soul-body relationship. For Ibn Sīnā, the soul is a substantial form of the body—a non-material substance that nevertheless interacts with and is influenced by the body. This interaction operates in two directions, and it is this dual influence that explains how love can manifest as both a spiritual perfection and a physical disease.
First, the body affects the soul: when the bodily faculties perceive something, or when the imagination forms an image, or when desire or anger is aroused, these bodily states give rise to corresponding states in the soul. If these states are repeated, they become stable dispositions (malakāt) that shape the character and inclinations of the soul. This explains how physical perceptions of beauty can give rise to powerful emotional states, and how repeated thoughts of the beloved can produce lasting patterns of thought and feeling.
Second, and equally important, the soul affects the body: when the soul experiences powerful emotions or forms intense imaginings, these psychological states produce corresponding effects in the body. Intense fear causes trembling; anger causes the blood to boil; the memory of a frightening event produces a rapid pulse. In the case of love, the soul's intense preoccupation with the beloved causes physical changes: the drying of bodily humors, changes in the pulse, and the other symptoms Ibn Sīnā describes. The soul's state is literally embodied.
This two-way interaction means that love cannot be understood as purely spiritual or purely physical; it is always a psychosomatic phenomenon. When love remains within its natural and proper bounds—the love of God or the love of the Absolute Good—it brings spiritual perfection and does not produce disease. But when love becomes focused on physical beauty in an excessive and obsessive way, the soul's preoccupation produces physical disturbances that manifest as a disease of the body. The same underlying capacity for love, which in its highest expression is the motive force of the cosmos and the path to divine proximity, becomes pathological when it operates at the animal level without the guidance of reason and law.
Ibn Sīnā's medical account of love provides, in effect, a diagnosis of love operating at the lowest level of the hierarchy—the level of animal desire and physical obsession—and demonstrates the physical consequences of this pathological manifestation. His philosophical account, by contrast, presents love in its full ontological range, from its most degraded and pathological forms to its most elevated and perfect expression in the Divine Essence. The two perspectives are not contradictory; they are complementary, each revealing a different dimension of love depending on the level of existence at which it manifests.

Conclusion
This study has examined Ibn Sīnā's treatment of love in his philosophical and medical writings, demonstrating that far from being contradictory, his two perspectives constitute a coherent and integrated understanding of love as a phenomenon that manifests differently across the ontological hierarchy. In his philosophical-mystical thought, Ibn Sīnā presents love as a universal cosmic principle that pervades all of existence, from the simplest inanimate substances through vegetative, animal, and human souls to the Divine Essence itself. Love, in this framework, is the innate drive of every being toward its own perfection and toward the Absolute Good, and it serves as the motive force for all movement and change in the cosmos. The highest and most perfect form of love is the love of God, which is both the source and the goal of all existence.
In his medical thought, Ibn Sīnā presents love as a specific psychological-physical disease characterized by obsessive thoughts of the beloved, physical symptoms such as hollow eyes, dry skin, irregular pulse, and behavioral symptoms including alternating joy and sadness. He provides detailed diagnostic methods, including the remarkable pulse-diagnosis technique, and practical therapeutic recommendations. The limitation of his treatment to men reflects the social constraints of his era but does not undermine the sophistication of his medical analysis.
The two perspectives are reconciled through Ibn Sīnā's theory of the soul-body relationship. The soul and body interact in two directions: the body affects the soul through perception, imagination, and emotion, while the soul affects the body through the power of mental states to produce physical changes. When love operates at the animal level, focused on physical beauty and excessive desire, it produces the physical symptoms of disease. When love operates at higher levels, directed toward the Absolute Good, it produces spiritual perfection. Love in itself is not a disease; it is a fundamental principle of existence. But when it manifests at the level of the animal soul and becomes excessive, it produces physical symptoms that the physician must treat. Ibn Sīnā thus demonstrates the unity of his intellectual vision, integrating philosophy, mysticism, and medicine into a comprehensive understanding of human experience, and affirming that the same phenomenon can appear as both the highest perfection and as a disease, depending on its level of manifestation and the context in which it operates.
