Quote by Bertrand Russell
In a man whose reasoning powers are good, fallacious arguments are evidence of bias. p. 67.
Summary
This quote suggests that when a person's ability to reason is sound and logical, the presence of fallacious arguments can indicate a hidden bias or ulterior motive. In other words, someone with strong reasoning skills should be able to recognize flawed arguments and identify the underlying personal bias or prejudice that may be influencing them. It implies that the use of fallacious reasoning can be a way of manipulating or distorting the truth when convincing and persuading others.
