This quote by Robert Louis Stevenson suggests that fear or cowardice can spread easily among people, much like an infectious disease. It implies that when one person shows fear, it can cause others to become fearful as well, leading to a collective sense of cowardice.

However, Stevenson also offers a counterpoint, stating that argument, or the act of debating and defending one’s point of view, can serve as a powerful tool to bolster courage. This suggests that engaging in intellectual discourse can help individuals overcome fear or hesitation, and instead, instill confidence and bravery.

In essence, Stevenson is highlighting the contrasting impacts of fear and argument on human behavior and emotions. While fear can lead to widespread cowardice, argument can inspire courage, making it a potent antidote to fear.

In today’s world, this idea is highly relevant. In the face of challenges or adversity, it is easy for fear to take hold and spread, causing panic and inaction. However, engaging in open dialogue, debating different viewpoints, and standing up for one’s beliefs can serve to embolden individuals and communities. It can inspire people to confront their fears and take decisive action, rather than succumbing to cowardice.

In terms of personal development, this quote encourages individuals to engage in critical thinking and open dialogue as a means to overcome fear and develop courage. It suggests that by challenging ourselves to defend our beliefs and perspectives, we can grow stronger and more confident. This can be applied in various aspects of life, from personal relationships to professional settings, where the ability to argue effectively and confidently is a valuable skill.
