Claim: In 1860. Charles Sanders Peirce began his semiotic theory and devised his three category system and determined a sign depends on its object which determines the sign but now when there is a row of toppling dominoes.
Evidence: Charles Sanders Peirce began writing on semiotics, which he also called semeiotics, meaning the philosophical study of signs, in the 1860s, around the time that he devised his system of three categories. The interpretant depends likewise on both the sign and the object—the object determines the sign to determine the interpretant. But this determination is not a succession of dyadic events, like a row of toppling dominoes; sign determination is triadic.
