Chapter 1: Understanding the Common Sense Defense

We’ve all heard it: “I already know this; it’s just common sense.” It’s a phrase often tossed around during discussions, training sessions, and educational events. But let’s pause for a moment. This statement is quite bold when you think about it. Essentially, the speaker is asserting:

“There’s nothing here that I haven’t already encountered, learned, or perfected.”

“They are claiming that your entire life experiences and education offer them nothing new, as they have mastered it all.”

Take a moment to reflect on this assertion. When you vocalize it, it sounds quite absurd. By making such a claim, you ironically highlight the very opposite of what you’re asserting. That’s one strike against the notion.

Section 1.1: The Value of Knowledge

This claim of possessing “common sense” inadvertently suggests that the information is less significant simply because it's widely known. The crucial question to ponder is: “Is the knowledge I profess to have demonstrated through my actions?”

If the answer is ‘No,’ then it doesn’t matter how much you ‘know.’ It quickly loses its value—not entirely worthless, but certainly diminished. That’s strike two.

Subsection 1.1.1: The Distinction Between Knowing and Doing

Knowledge is a powerful tool. Strive to acquire as much as you can and continue learning. However, it’s essential to recognize that knowing and doing are two entirely different concepts. We all have an abundance of knowledge, but that doesn’t guarantee that we apply it consistently in our daily lives.

Merely knowing or discussing a subject isn’t enough; you must take action. Transforming common knowledge into uncommon results is a rarity. True success in any area demands that we take our common sense and put it into practice.

Those who fail to close the gap between knowledge and action often fall victim to what I refer to as the “Common Sense” Defense. This is a psychological mechanism, either conscious or subconscious, used to cope with feelings of disappointment regarding lack of progress or achievement.

This behavior acts as a shield against the discomfort of self-reflection. Many would rather avoid this discomfort at all costs, often resorting to the easy route of claiming “common sense.”

“Common sense is the collection of prejudices acquired by age 18.” - Albert Einstein

Section 1.2: The Smoking Paradox

Take smoking as a clear example. There’s no debate that smoking is detrimental to health; it’s a well-known fact. Yet, despite this common understanding, millions continue to smoke. This contradiction highlights that while some truths are easy to grasp, they can be incredibly challenging to act upon.

If your claimed knowledge isn’t reflected in your actions—if others can’t observe it in your behavior—then the validity of that knowledge is questionable.

So, refrain from using the term “common sense” when, in reality, it might be anything but that. Instead of merely stating what you think you know, start illustrating it through your daily actions.

Chapter 2: Moving Beyond Common Sense

The first video, "Common Sense Self Defense - Episode 1," delves into practical self-defense techniques and highlights the importance of applying knowledge effectively.

The second video, "Partially Examined Life #307: G.E. Moore Defends Common Sense (Part One)," offers a philosophical perspective on the concept of common sense and its implications in our lives.

To everyone who believes they know it all: keep learning, because you may be the ones who need it the most. Otherwise, that’s strike three—you’re out.
