A crucial branch of philosophy is logic, which is still very relevant today. It has been around for many centuries and has been very much discussed in medieval times of course. It has of course changed over times, just as its purpose has changed. But what has not changed is that it helps us strengthen our arguments and keeps us from making mistakes in our reasoning. Logic was very much a discipline during the medieval period, there were many thinkers that dedicated most of the works towards this discipline. Of course, a lot of logic was used to make arguments about God and other religious topics, since philosophy and theology were very much entwined. We might wonder if medieval logic is still therefore still relevant today, but of course it is. Firstly, many problems medieval logicians were dealing with are still unresolved today, as has been shown in the lecture; we can still debate the liar paradox and not come to any conclusion of whether what is being said is true. Logical problems are something that stay pretty constant over time, though language evolves many logical puzzles have stayed with us over time. Medieval logic has just as ancient logic provided us with a foundation of the building that is modern logic.
Not necessarily having to do with logic, but what is also interesting to see how medieval thinkers wrote commentaries especially when we look at censorship in modern society. Medieval thinkers wrote commentaries on works of previous thinkers, in which they hid their own new ideas because they were only meant for the intellectual elite, and not the masses. It is interesting to think how this way of introducing new ideas only meant for a certain target audience. In states such as North Korea and China where there is a high level of censorship, critics of the regime might also be forced to bring new ideas into the world hidden in other works.
Medieval logic is still very relevant today, we should not forget or dismiss that the logic we now have is always based on what has come before.
