Quote
“Those that know, do. Those that understand, teach.”
Explanation
In this quote, Aristotle distinguishes between knowledge and understanding, suggesting that those who possess practical knowledge—the ability to apply what they know—act and perform tasks, while those who have a deeper understanding—the ability to explain and impart knowledge—become teachers. Knowledge involves knowing how to accomplish something, often through hands-on experience or practical application, while understanding implies a more profound insight into the subject, one that enables a person to explain, communicate, and teach others. According to Aristotle, true understanding is not just about knowing facts but about grasping concepts deeply enough to pass on that knowledge in a meaningful way.
This idea remains relevant today, especially in the context of education and leadership. The best teachers and leaders often have a deep understanding of their fields, allowing them to teach others not only through instruction but by helping them understand the principles behind actions and decisions. In contrast, those who are simply skilled or knowledgeable in a particular task may be able to perform the task well but may lack the ability to explain or guide others in understanding it.
For example, a skilled chef might know how to cook a dish perfectly, but a great culinary instructor can explain the techniques, science, and art behind the dish, helping others understand how to replicate it. Similarly, a successful entrepreneur may know how to run a business, but a seasoned mentor is someone who not only has experience but also understands why certain business strategies work and can teach others to apply those principles. Aristotle’s quote reminds us that teaching requires a deeper level of insight and the ability to make complex ideas accessible to others, and is not simply about doing.
