In logical analysis, spectral variables are the hidden premises, unstated assumptions, and implicit contexts that determine whether an argument actually works. Formal logic deals with explicit premises and valid inference forms. But real arguments live in the spectral space between the lines: the shared cultural knowledge that makes an analogy land, the emotional weight that gives a premise force, the historical context that makes a conclusion feel inevitable. Logical spectral variables are why the same formal argument can be persuasive in one setting and laughable in another—the logic hasn't changed, but the ghosts have.
Spectral Variables (Logic) "Your syllogism is formally valid, but it's haunted by a Spectral Variable: you're assuming everyone defines 'freedom' the way you do. Change that ghost, and your conclusion vanishes. Logic isn't just about form—it's about what's haunting the premises."
