What are basics; What are fundamentals?

It is imperative I relay that this particular post answer is a set of direct quotes from Marc MacYoung's book on Effective Offense. See the Bibliography and notes as you read. I have found this book to be most informative. It has focused a spot light on issues often not taught or lost in training and practice.

"A basic is an introduction. A fundamental is a foundation. A fundamental is a premise, idea, or fact that an entire system arises from and is based on. A fundamental determines the shape of  what arises from it, much as a foundation of a house dictates its layout. A basic is how you introduce people you are teaching to the system. It is a beginning concept, often simplified to assist learning. If a fundamental is the foundation, a basic is the front door to enter the system." - Marc MacYoung - Secrets of Effective Offense - Chapter Eight: Blocking and Deflecting - page 124.

You practice basics so you can ingrain fundamentals. The novice, beginner, works on the gross movement; advanced practitioners focus on different aspects, making little tweaks and adjustments. Basics can be learned in five minutes, but fundamentals can take years to fully understand. - Marc MacYoung - Secrets of Effective Offense - Chapter Eight: Blocking and Deflecting - page 124 and 125.

In training facilities that make no distinction between these two terms, people rush past the basics hoping to get to the "good stuff." When told they need to pay attention to the "basics," they dismiss the idea as too rudimentary, not realizing the difference between a fundamental and a basic. - Marc MacYoung - Secrets of Effective Offense - Chapter Eight: Blocking and Deflecting - page 125.

In doing so, they ignore the fundamentals and do not ingrain them into their consciousness and reactions. Then they wonder whey what they are trying to do falls apart in a fight. - Marc MacYoung - Secrets of Effective Offense - Chapter Eight: Blocking and Deflecting - page 125.
