Symbonic is the Academy’s discipline of symbolic synthesis. Players are dealt a hand of symbols drawn from a curated lexicon — mathematical signs, alchemical glyphs, musical notations, ideograms, fragments of natural language — and asked to compose, from any subset of them, a coherent statement whose meaning a second player can recognise and respond to. The game has no fixed grammar; each composition proposes its own. The Academy hosts Symbonic in tribute to Leibniz’s lifelong ambition for a characteristica universalis: a notation in which the structure of any thought could be expressed and any disagreement reduced to a calculation. The game is a play form of that ambition — finite, social, and self-correcting. To play it is to discover, again and again, how much of meaning is what is meant rather than what is said.
