It seems to me that the act of searching for truth, finding truth, and expressing truth is all just transformations of matter (and energy). For example, suppose I am proving some mathematical theorem. The "proving" is just molecular interactions in my brain that cause rewiring of neurons. The belief that my proof is successful is just more molecular interactions in my brain. Expressing the theorem is just talking (creating sound waves) or writing (creating patterns of ink on paper).
If all of this "proving" is just transformations of matter according to physical laws, then how is any truth being discovered? And how can any truth exist? It seems like Andrew Wiles proving Fermat's Last Theorem is fundamentally no different than a slinky walking down some stairs or an ice cube melting in the sun.
When Andrew Wiles publishes his proof of Fermat's Last Theorem and other people read it, they may feel good about what they have read and call it "truth", but again that is just because of the molecular interactions in their brains and bodies. And now that they have read the proof, all that has changed are some connections between neurons in their brains. Can one lump of matter (the brain after reading the proof) contain more "truth" than another lump of matter (the brain before reading the proof)? Does a lump of clay contain truth?
