Non-classical logic

Free logic

A free logic is a logic with fewer existential presuppositions than classical logic. Free logics may allow for terms that do not denote any object. Free logics may also allow models that have an empty domain. A free logic with the latter property is an inclusive logic. (Wikipedia).

Logic: The Structure of Reason

As a tool for characterizing rational thought, logic cuts across many philosophical disciplines and lies at the core of mathematics and computer science. Drawing on Aristotle’s Organon, Russell’s Principia Mathematica, and other central works, this program tracks the evolution of logic, be

Scott Aaronson - Physics of Free Will

Free will has traditionally been a problem in philosophy. Recently, the battleground of free will has shifted to neuroscience. Now some claim that to solve the problem of free will, we must go far deeper, to the fundamentals of physics, down to subatomic forces and particles. But don't fre

What are Non-Classical logics?

Some of the general classes of non-classical logics I touch in this videos are linear logic, relevant logic, modal logic, many-valued logics, minimal logic, paraconsistent logics and so on and so forth. Let me know if I should dive deeping into a certain scene? https://en.wikipedia.org/wi

You don't have free will, but don't worry.

In this video I explain why free will is incompatible with the currently known laws of nature and why the idea makes no sense anyway. However, you don't need free will to act responsibly and to live a happy life, and I will tell you why. Support me on Patreon: https://www.patreon.com/Sabi

Paul André Melliès - Dialogue Games and Logical Proofs in String Diagrams

After a short introduction to the functorial approach to logical proofs and programs initiated by Lambek in the late 1960s, based on the notion of free cartesian closed category, we will describe a recent convergence with the notion of ribbon category introduced in 1990 by Reshetikhin and

Matthews Grant - Does God’s Knowledge Quash Free Will?

How can God's perfect knowledge not eliminate free will? Since God-to-be-God can never be wrong and knows everything, including propositions about future events, how can those propositions about future events, which God knows now, not come to pass in the actual future? Hence, if we cannot

Semistructured data is an umbrella term encompassing data models which are not logically organized in tables (i.e., the relational data model) but rather in hierarchical structures using markers such as tags to separate semantic elements and data fields in a ‘self-describing’ way. In this

Lecture 9: Higher-order logic and topoi (Part 2)

Most of this talk was spent defining a higher-order logic, which Lambek and Scott call a "type theory". At the end it was explained how to organise certain terms of such a logic into a category, which next time we will prove is a topos. The lecture notes are available here: http://theris

Basic Methods: We define tautology and contradiction and consider the conditions of logical equivalence and implication. Examples include DeMorgan's Laws for logic, modus ponens, and the Law of the Excluded Middle. As a final note, we introduce the Substitution Rules.
