Critical thinking

From television stories to personal experiences, we live in a world where honesty seems to be an increasingly rare commodity and suspicion and scepticism become protective shields.

A circular argument is an argument forming part of a thesis which has not been established, but still needs to be argued for.

In our everyday lives we ​​often resort to simply repeating what has been said or done before. But not everything that is old is authentic or correct. When we refer to tradition with full confidence that the way it was understood and acted on in the past is self-evident, we are committing the logical error of appealing to tradition, or false induction.

We live in a polarised world where conspiracy theories proliferate, but some people are more inclined than others to consume and propagate these theories rather than ignore or demystify them.

Even if we have not been to Eden, the longing for innocence draws us back to a time when we had not yet tasted the forbidden fruit.

The ability to imagine alternatives to events that have already occurred distinguishes humans from other creatures and machines—artificial intelligence has not yet succeeded in creating a device that can devise counterfactual scenarios. The fact that we can travel in an imaginary time and rewrite our actions and their outcomes can prove to be an advantage or can lead to dysfunctional emotional and cognitive...

Needing to process a multitude of complex information in a short amount of time can lead to erroneous reasoning. When a conclusion is supported by weak or irrelevant arguments, the reasoning falls into the category called non sequitur—does not follow, or irrelevant argument.

No one has ever seen a thought, not even a neurosurgeon. However, today we know more about the way we think than what we were able to visualise, yet still less than we would like to know.

When what someone says can be interpreted in multiple ways, we are in danger of coming to an understanding which is different to their intended message.

When we consider that a conclusion is founded only if a lot of people consider it true, we fall into the trap of the argumentum ad populum or the appeal to popularity.

Arguments must be convincing and, in order to convince, they must be valid—the minimum requirement of persuasion.

By their very complexity, situational moral decisions demonstrate that there is an absolute good that we seek. Moral principles work together for the absolute good.
