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.

"Happiness is not in the mere possession of money; it lies in the joy of achievement, in the thrill of creative effort." (Franklin Delano Roosevelt, US President)

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.

The moment we distort a person’s intention, statement, gesture or action for our own personal gain we are using, consciously or unconsciously, the straw man argument − a frequent fallacy.

Many of us probably know at least one manipulative person — or perhaps we’ve even caught ourselves falling into that category. But do we really know when this tendency to control or influence others becomes harmful? And more importantly, how can we deal with manipulative people?

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.

In practice, people often accuse each other of making logical errors, but sometimes the accusation is false.

From an early age I learned, from the advice of adults or from my own experiences—and sometimes the hard way—the relationship between cause and effect. It's simple: if you touch the hot oven door, you’ll get burned! Subsequently, I discovered that there are a multitude of pressing uncertainties all around us in daily life.

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.”
