Is defeasibility a limitation of our knowledge or does it provide a key to unlocking further truths?

Chantal Urian

Well, in my opinion, defeasibility is both a limitation of our knowledge and a key to unlocking further truths. Let me explain. Defeasibility refers to the idea that our beliefs and knowledge can be revised or even overturned when new evidence arises. This means that what we once thought was true, may not be true anymore.

On the one hand, this can be seen as a limitation of our knowledge, as it means that we cannot have absolute certainty about anything. For example, we may believe that the earth is flat, but then new evidence emerges that proves that it is actually round. Our previous belief was defeasible, and we had to revise our understanding of the world. This can be frustrating as it means that we can never be entirely sure that what we know is true.

On the other hand, defeasibility can also be seen as a key to unlocking further truths. If we were never able to revise our beliefs and knowledge, we would never be able to progress and learn new things. Science, for example, is founded on the idea of being able to refute or revise previous theories when new evidence arises. This is how we move forward and make new discoveries.

Furthermore, the process of defeasibility allows us to challenge our biases and assumptions. By being open to the possibility that what we know may not be true, we can approach new information with a critical and reflective mindset. This can lead to a deeper understanding of the world around us and even new discoveries.

Of course, this is not to say that defeasibility is always easy or pleasant. Having our beliefs overturned can be uncomfortable and even painful, especially if we have invested a lot of time and energy into them. However, I believe that it is a necessary and valuable part of the learning process.

In conclusion, while defeasibility can be seen as a limitation of our knowledge, it is also a crucial aspect of unlocking further truths. By being open to the possibility of revising our beliefs and knowledge, we can challenge our biases, approach new information with a critical mindset, and make new discoveries.
