Critical thinking

The appeal to ignorance (argumentum ad ignorantiam) is an error in thinking which argues that a conclusion is true because there is no evidence against it, or that a conclusion is false because there is no evidence in its favour.

In an argumentative discussion each party involved must be able to express their point of view without constraints, discrimination or other interferences. This is, in fact, an important prerequisite for the effort to overcome differences of opinion. In practice however, often things are far from this ideal. Not only do interlocutors not respect each other’s right to free speech, but they also resort...

In everyday life, whether we like it or not, we rely on the information provided by experts or specialists. However, no authority deserves blind trust. When we take someone's word for granted simply because that person is an authority, we make the logical mistake called "appeal to authority."

What we call an “irrelevant conclusion” is an argument that gives the impression of having something to do with an idea it aims to support, but which actually shifts attention to something else.

A few years ago, the American Statistical Association carried out research on the history of statistics, tracing their use throughout the course of human society’s development. The results of the study are displayed in the form of a chart called the Timeline of statistics, available on the association's website.

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.

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.

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

The false dilemma fallacy presents an issue as if there are only two ways to solve it—often, two opposite ways—when, in fact, there are more ways than that. The conflict between the two ways presented is also false.

Do your best to present yourself to God as one approved, […] who correctly handles the word of truth. (2 Timothy 2:15)

Almost a century ago, writer Virginia Woolf noticed people’s tendency to approach books “with clouded and divided minds, asking fiction to be true, poetry to be false, biographies to be flattering and history to chime with prejudices.”

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.

Critical thinking is not a cure-all, but it proves very useful in dealing with, clarifying, and solving some decision-making problems, as well as the thought and belief disputes which occupy our minds.

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.
