The Etymology of “the Etymology”

We are accustomed to a three-dimensional world. Our brains are so tethered to physical reality that even conceptualizing space-time as a fourth dimension can make us dizzy. Yet, without a second thought, we navigate complex structures with thousands of dimensions every single day: human language.

The architecture of this linguistic space is built on semantic vectors. "Big" and "small" do not exist in isolation; they sit on the exact same axis, representing different points on the axis of scale. In contrast, the words "North" and "West" are orthogonal to each other, acting as completely independent variables, while "Northwest" is a linear combination of the two. When we describe a "big red sweet apple," we are instantaneously locking onto a specific point defined by at least four distinct dimensions: size, color, taste, and type of fruit. It occupies the same four-dimensional vector space as “small green sour pear”.

The semantic mathematics becomes even more fascinating with complex concepts. If you add the coordinates of the vectors for "occupation" and "medicine," the resulting vector points in the region of the concepts like "doctor", “nurse” or pharmacist”, hinting that those words have are close to each other in the semantic vector space.

This vector space have thousands of dimensions. Even though not all words are orthogonal to each other, we need those dimensions to differentiate things and concepts from each other. However, despite such impressive dimensionality, this vector space is incredibly vast and sparse. Most of the words can be described by a few characteristics, defining their dimensionality. It means that for any given word, the vast majority of its vector coordinates are simply zeros; it has no relation to thousands of other active dimensions. The rest of the vector space remains uncharted territory. You can picture it as a colossal tree with a lot of orthogonal branches and very few non leaves. Language operates as a colossal, largely empty matrix where our minds continuously draw lines between active nodes, utilizing high-dimensional math to compress, map, and communicate reality.

The evolution of language is not merely a history of communication; it is the history of human progress and cognitive expansion. Early language initially emerged to address immediate and concrete needs, as a local convention signaling threat, food, or shelter. Over time languages grew in volume and dimensions, allowing for more precise communication and better description of the reality. The true power of language revealed itself with the addition of abstractions, concepts or objects which had no physical manifestation. Every time a new abstract concept was named, a new axis was added to our collective cognitive vector space, further expanding the vector space of possibilities and refining our perception of reality.

This is the essence of phantasy or imagination is to combine existing concepts to map coordinates in the "empty" spaces of the matrix, using this expanding multidimensional vector space, generating synthetic data. Interestingly enough, we could deduce the properties of newly created artefacts by analyzing its vector language coordinates. It fueled scientific discoveries and technological progress. Two hundred years ago, combining the vectors for "carriage", “motor” and “sky" resulted in a conceptual void. Yet today, the "airplane" is a dense, universally understood node in our daily reality. We did not simply stumble into the sky; we mapped the coordinates in our minds first.

Science fiction serves precisely this function at a societal level. It is synthetic training data used to stress-test reality. By projecting linguistic vectors into the unchartered territory, extrapolating trends in physics, society, and technology, science fiction allows us to simulate futures before we endure them. Countless inventions, from the mobile phone to satellite communication, were not just engineered; they were pulled into existence because science fiction first carved out the conceptual space for them.

This dynamic creates a perpetual, self-sustaining engine of progress. The relationship between what we build and what we dream is not a one-way street, but an integrated loop: reality is driven by imagination, and imagination is driven by reality.

Reality provides the foundational vocabulary, reflecting what is possible today and providing raw data of our current existence. Imagination uses the vector space of language to combine this data into novel, synthetic concepts. Science and Engineering pull these imagined concepts down into the physical world. The physical world expands, providing a new baseline reality, which immediately fuels a higher, more complex tier of imagination.
