TY - JOUR AU - Joaquin, Jeremiah Joven PY - 2022/10/25 Y2 - 2024/03/29 TI - Immune Logics ain't that Immune JF - Logic and Logical Philosophy JA - LLP VL - 32 IS - 2 SE - Articles DO - 10.12775/LLP.2022.029 UR - https://apcz.umk.pl/LLP/article/view/37263 SP - 253-259 AB - <p>Da Ré and Szmuc argue that while there is a symmetry between ‘infectious’ and ‘immune’ logics, this symmetry fails w.r.t. extending an algebra with an immune or an infectious element. In this paper, I show that the symmetry also fails w.r.t. defining a new logical operation from a given set of primitive (Boolean) operations. I use the case of the material conditional to illustrate this point.</p> ER -
