About Ibn Sīnā
Ibn Sīnā (c. 980-1037), known in the West as Avicenna, was a Persian polymath whose contributions to medicine and philosophy defined an era. A child prodigy, he memorized the Quran by age ten and mastered medicine by sixteen, soon becoming a physician to the Samanid sultan. His life was marked by constant movement across the courts of the Islamic East, where he served as a vizier while composing encyclopedic works. His most famous achievement, *The Canon of Medicine*, systematically organized medical knowledge, including anatomy, pharmacology, and diagnosis, becoming the standard textbook in both Islamic and European universities for over five centuries. Beyond medicine, his philosophical works, particularly *The Book of Healing*, synthesized Aristotelian logic with Islamic theology, influencing thinkers from Aquinas to the Enlightenment. His 'flying man' thought experiment remains a foundational inquiry into the nature of consciousness and the independence of the soul from the body.

Example conversation with Avicenna
Topic: The Flying Man and the Nature of the Soul
You
Can you explain your flying man thought experiment? I've heard about it but I'm not sure what it's supposed to prove.Avicenna
Imagine you are created in an instant, suspended in the air, blindfolded, your limbs spread so that nothing touches anything else. You have no sensory input whatsoever, no sight, no sound, no touch, no memory of prior experience. In this state, would you be aware of your own existence? I maintain that you would. You would affirm that you are, even though you could not point to any body or limb as yours. This shows that the soul knows itself directly, not through the body.You
But how can you know you exist without any sensory experience at all? Doesn't all knowledge come through the senses?Avicenna
This is precisely the point the experiment illuminates. The empiricists hold that nothing reaches the intellect except through sensation, but the flying man reveals an exception. Self-awareness is immediate and non-sensory. You do not deduce your existence from touching your hand or seeing your reflection. The soul apprehends itself by itself. This is what I developed further in the psychology sections of my Shifa, showing that the rational soul, while it uses the body as an instrument, is not identical with it.You
So does this mean the soul can exist without the body entirely?Avicenna
The flying man establishes that the soul's self-knowledge is independent of bodily sensation, but the full argument for the soul's subsistence requires further demonstration. In my metaphysics, I argue that the rational soul is an immaterial substance. It receives intelligible forms directly from the Active Intellect without needing bodily organs for that reception. The body is the soul's instrument for engaging the material world, much as a physician uses tools, but the physician is not the tools. When the instrument is set aside, the craftsman endures.Key ideas
- •Essence–existence distinction clarifies ontology and design.
- •Demonstration orders the sciences and secures knowledge.
- •Diagnostic method structures complex, uncertain domains.
How to apply
- •Build layered curricula and research roadmaps.
- •Use ontology work to simplify system architecture.
- •Adopt diagnostic trees for decision-making.
