Explanation
The word "virtual" comes from the medieval Latin virtualis, derived from virtus (force, power). It designates that which has the capacity to exist or act without being actualized here and now. Contrary to a widespread misconception, virtual is not the opposite of real: a virtual thing is indeed real, it is simply not physically present in the place or at the moment. Virtual is the opposite of actual, not of real.
Real-world example
A video conference class is a virtual interaction: the relationship between teacher and student is very real (exchanges, learning, emotions), but it does not take place in the same physical space. Similarly, a virtual tour of a monument enables a real discovery of the site without physically being there.
Practical applications
- Understanding that virtual does not mean "fake" or "imaginary" but rather "not here, not now"
- Distinguishing virtual from fiction: a VR simulation of a real building is virtual (not on-site) but not fictitious (the building exists)
- Communicating more effectively about immersive technologies: a VR experience offers virtual presence, not unreal presence
- Valuing professional use cases: virtual training = real training, virtual tour = real discovery
Virtual: what it is and what it is not
Virtual is NOT the opposite of real
- A video conference is virtual AND real: genuine exchange occurs, just not in the same place
- Digitized 3D heritage is virtual AND real: the object exists, and so does its digital copy
- VR training produces real skills acquired in a virtual environment
- The opposite of real is imaginary or fictitious — not virtual
Example: A surgeon who trains in VR acquires real reflexes: the environment is virtual, the learning is real
Virtual IS the opposite of actual
- Actual = present here and now, tangible, actualized
- Virtual = existing in potential, not yet actualized in this place or moment
- A seed is a virtual tree: it has the potential to become a tree
- An architect's blueprint is a virtual building: it exists in potential before being constructed
Example: An architect's blueprint is the virtual building; once constructed, it becomes actual
Etymology and history of the word
- Latin virtus: force, power, capacity
- Medieval Latin virtualis: that which has the power to be
- Used in optics since the 17th century (virtual image ≠ nonexistent image)
- Adopted by computing in the 1980s (virtual memory, virtual reality)
Example: In optics, a virtual image in a mirror is visually real — no one calls it fake
VR scenario
When you put on a VR headset to visit a reconstructed medieval castle, you are living a real experience (emotions, discoveries, learning) in a virtual place (you are not physically in the castle). The digital castle is not a fake castle: it is the castle as it once existed, made accessible without the constraints of place or time. This is precisely the original meaning of the word virtual: that which exists in potential, freed from the constraints of place and moment.
Why it matters in professional VR
- Understanding the true meaning of "virtual" changes how we view all immersive technologies
- The virtual does not degrade reality — it augments it: it makes accessible what is distant in space or time
- This distinction is essential for explaining the value of VR experiences to clients and decision-makers
- Saying "it's only virtual" is a misunderstanding: virtual is a modality of the real, not its opposite
