Self referential, emergent, and ascending dimensions: A philosophical discussion from Bach to Bitcoin Music, as an abstract art form, can deeply touch the human soul. Bach's "Maze of Harmony", with its exquisite violin concerto in D major, is an example. Listening to this piece feels like being in a maze full of recursive loops, where the stacking and swirling of notes create ripples in the hearts of both the listener and the performer. This "stacked" psychological experience is like climbing an endless ladder, with each step containing a repetition and continuation of the previous one, and finally experiencing the sudden enlightenment of "another village in the midst of the melody's twists and turns". This feeling can be described as' jumping out of one's own finger '. It is not only a depiction of musical structure, but also a metaphor for the state of the mind. Just as Wang Wei's poem "Walking to the end of the water, sitting and watching the clouds rise" and Su Shi's "Lushan Smoke and Rain Zhejiang Tide" both contain a sense of liberation from difficulties and transcendence from the cycle. This recursive loop, this seemingly closed 'self reference', often nurtures new possibilities and leads us towards a broader realm. However, 'self reference' does not only exist in music and poetry. It is a profound philosophical concept that touches upon life, meaning, and our understanding of reality. G ö del's incompleteness theorem is the most rigorous mathematical expression of "self referential". He used formal language to reveal the boundary between life and non life, meaning and meaninglessness, and the key to this boundary lies precisely in "self reference". G ö del's discovery, like a torch illuminating the darkness, brought to light humanity's long-standing vague perception of intuition. Bach uses music, Escher uses painting, and Satoshi Nakamoto uses Bitcoin, all exploring and expressing the concept of "self reference" in their own ways. Escher's print "Concave and Convex" is an excellent visual example. He cleverly uses perspective and spatial illusions to create an architectural scene full of visual paradoxes. The interweaving of concave and convex surfaces makes it difficult for viewers to distinguish which parts protrude forward and which parts are concave backward. This visual uncertainty is not only a challenge to our perceptual abilities, but also a profound questioning of the essence of reality. Escher's works remind us that the reality we perceive is not an absolute objective existence, but is influenced by our perspectives, experiences, and cognition. And Satoshi Nakamoto's Bitcoin has pushed the concept of "self referential" to another level. He designed a decentralized cryptocurrency system, in which the computing power input of miners constitutes the "self referential" layer of the system. Miners maintain the security and operation of blockchain by solving complex mathematical problems and competing for accounting rights. This self referential cycle enables the Bitcoin system to sustain and strengthen itself. However, the value of Bitcoin does not solely come from the computing power input of miners. It also comes from its scarcity, decentralized nature, and its function as a store of value and a medium of exchange. These characteristics constitute the "emergence" layer of Bitcoin, which transcends the individual behavior of miners and forms unique economic and social significance. The brilliance of Satoshi Nakamoto lies in his clever combination of "self pointing" and "emergence" to create a system that is both vibrant and has real value. The self referential behavior of miners provides the foundation for the emergence of Bitcoin; The emerging value of Bitcoin, in turn, motivates miners to engage in self referential behavior. This double-layer structure design enables Bitcoin to sustain and develop on its own, like an organic life form. However, understanding only "self reference" and "emergence" is not enough. To truly break free from the limitations of self referential thinking, we need to 'elevate dimensions' or, in other words, examine from the perspective of the' emergence layer '. Miners are within the Bitcoin system and can only see local transactions and blocks, without knowing the full picture of the longest chain. But as observers with a global perspective, we can easily grasp the overall context and see the overall operation of the Bitcoin system. This perspective of "dimensionality enhancement" allows us to transcend local and individual limitations and see a broader picture. As Hou Shida tells the story of Bach's dying, Bach's death is a transcendence of his self referential life. When he dictated unfinished movements, his life merged with his music, transcending the limitations of individual life and resonating in a broader time and space. Isn't life itself a self referential cycle? We are trapped in our own perspective and find it difficult to escape. However, through art, science, or a profound understanding of the meaning of life, we may be able to glimpse higher dimensions, like the immortal melodies left by Bach in music, transcending individual life and resonating in a broader time and space. Therefore, understanding "self reference" and "emergence", and learning to "elevate" thinking, can not only help us better understand art, science, and technology, but also inspire us to deeply reflect on life, meaning, and existence. From Bach's music, to Escher's paintings, to Satoshi Nakamoto's Bitcoin, these seemingly different fields all contain the same philosophical thinking. And it is these thoughts that lead us to constantly surpass ourselves and explore broader unknown fields.
