This video discusses the basics of logic and how it can be applied to philosophical questions. It introduces the concept of an argument and provides an example of how an argument can be used to examine a philosophical question. The video concludes by noting that one of the exercises in the logic cafe is not an argument.

00:00:00 This lecture discusses the concept of philosophy, explaining that it involves questions about knowledge and the existence of knowledge. It also discusses the different types of philosophy, including academic philosophy, which encompasses a wide range of topics. Finally, the lecture discusses the idea of a philosophy of life, which is a conceptual framework that includes assumptions about the nature of life.
00:05:00 This video discusses what philosophy is, and how it relates to other disciplines such as mathematics and physics. It then goes on to discuss the different degrees that are typically associated with philosophy, and why they are considered to be the most advanced degrees in their respective fields. Finally, the video discusses what philosophy is specifically, and how it can be used to examine questions and issues that don't yet have clear-cut answers.
00:10:00 In this lecture, Dr. Max teaches the basics of symbolic logic, including the concepts of basic logic and propositional logic. He then goes on to discuss the history of philosophy and how philosophers have asked and attempted to answer difficult questions. Finally, Dr. Max discusses how, if questions have clear-cut answers, philosophy can be eliminated from the field.
00:15:00 Logic is a way to push clear-cut answers in philosophy, and it has a formal structure that allows reasoning to move from truths to truths.
00:20:00 In this lecture, Professor Lewis explains the purpose of logic and philosophy and how they relate. He goes on to discuss the proof of one equals two, which is a situation where the reasoning seems plausible at first but eventually becomes absurd. He discusses how logic and philosophy can help us learn about our beliefs and how to change them.
00:25:00 Logic is important to philosophy because reasoning is central to it, and the logical connectives allow for different interpretations of a sentence.
00:30:00 In this video, John Halpin of the Logic Cafe discusses the use of logic in philosophy and the various philosophical questions that can be asked about logic. He also introduces the concept of truth tables, which are a way of representing the truth or falsity of propositions. He goes on to explain that every sentence, proposition, and statement in philosophy must be either true or false, but goes on to mention that there are certain situations where this is not the case. He finishes the video by discussing the concept of infinite valued logic, which is a type of logic that goes beyond the two value system that we are most familiar with.
00:35:00 This video provides a basic introduction to the concepts of logic, with a focus on deductive reasoning. Valid arguments are defined, and examples of valid and invalid arguments are provided.
00:40:00 The lecturer discusses the concept of soundness, which is the ability of an argument to be both valid and have only true premises. He then provides an example of an argument that is valid but not sound, and points out that logic alone does not provide a clear path to determining the soundness of an argument. He goes on to discuss the concept of validity, which is a formal consideration that follows from the logic of an argument. Finally, he discusses the difference between logic and the sciences, noting that while logic provides a structure within which we can make inferences, the sciences are responsible for actually discovering the truth or falsity of propositions.
00:45:00 This lecture provides an introduction to the principles of logic, starting with five basic axioms. These principles were developed by Euclid, a student of Aristotle. Euclid's axioms and definitions were apparently intuitively obvious, and from them he was able to derive a wide range of surprisingly complicated conclusions. This type of impossibility is called a "special type of impossibility."
00:50:00 This video introduces the basics of logic, including the concepts of premises and inference. It then discusses how deductive and inductive reasoning works, and provides a sample argument. The video asks students to break the argument down into its formal standard form, and provides tips on how to do so.
00:55:00 The video discusses the basics of logic, including the concept of an argument, and offers an example of an argument. It notes that an argument may not be complete, and offers a solution to a problem. The video concludes by noting that one of the exercises in the logic cafe is not an argument.

01:00:00 - 01:05:00

This lecture provides an introduction to the basics of logic, including the definition of a sound argument and how to demonstrate that an argument is sound. The presenter also goes over how to use letters to identify a given argument's validity and false premises.
