Knowledge, the ultimate alloy

Knowledge is an alloy of theory and experience, strengthened by curiosity, imagination, and sharing. Drawing from diverse disciplines and questioning dogma enhances understanding.

THE IDEA

Knowledge, the ultimate alloy

When we reflect on our knowledge, we recognize that it has component parts. At the very least, we can easily appreciate that there is knowledge we have gained from direct experience, and knowledge we have gained from theory, like that from books. Knowledge about when a stove is hot is often gained firsthand in our early years, but how that heat is produced is something we later learn in a science textbook.

Furthermore, most of us appreciate that to only learn from others, or to only credit that which is gained from direct experience would both be functionally useless. A scenario in which you could only learn from one or the other would not produce the alloy we call knowledge. Theoretical learning cannot prepare you to understand all the nuances of your particular life, such as your partner or the dynamics of your team. And if you relied solely on your own experiences to learn, you would be condemned to repeat the mistakes of others, which is extremely ineffective. Theory and experience together create knowledge, and both serve to augment and advance the capabilities of the other. Experience can trigger the updating of theory, and the validation or application of theory can trigger new experiences.

The alloy that is knowledge can further be conceptualized with more complexity. Aristotle* discussed five components of knowledge. “They are what we today would call science or scientific knowledge (episteme), art or craft knowledge (techne), prudence or practical knowledge (phronesis), intellect or intuitive apprehension (nous) and wisdom (sophia).”6 These components of knowledge were not mutually exclusive; they reflect the understanding of how much knowledge we bring to bear on any given situation. When driving, we understand the rules of the road and how to operate the machine. We further understand how road conditions are likely to impact our drive, both in terms of the vehicle handling and time of journey. We also factor in how other drivers are likely to respond in the variety of circumstances we could possibly face as we progress to our destination. The sources of our knowledge are varied.

To really explain knowledge as an alloy, something that is strengthened when we mix certain components in, we can look at the life of Leonardo da Vinci.* In Walter Isaacson’s account, he explains that Leonardo was able to conceive of things in an extraordinary way leading him to discover or validate concepts that were often hundreds of years ahead of his time.7

Leonardo was curious; he wanted to know how the world worked and why. He also possessed and honed the skill of intense observation, studying birds and plant stems for hours, or making extensive notes and drawings on eddies of water and optics. He would observe a phenomenon, make a guess as to the principles behind it, and seek to validate those through further observation. Leonardo was willing to challenge accepted truths, seeking to understand them by questioning them. “His lack of reverence for authority and his willingness to challenge received wisdom would lead him to craft an empirical approach for understanding nature that foreshadowed the scientific method developed more than a century later by Bacon and Galileo.”8

He was mainly self-taught, having had almost no formal schooling, but he recognized the value of learning from the experiences of others. A quote from one of his journals reads, “Get the master of arithmetic to show you how to square a triangle.…Ask Benedetto Protinari by what means they walk on the ice in Flanders…Get a master of hydraulics to tell you how to repair a lock, canal and mill in the Lombard manner”9 These notes suggest that no one has the time to do everything, and the alloy that is our knowledge must contain what we can learn from others.

Leonardo also readily combined knowledge from different disciplines, his understanding of nature informing his art, or his theatrical experiences pushing him to understand more about optics. His interdisciplinary approach strengthened his knowledge by giving it a varied practicality and usefulness. “Thus, Leonardo became a disciple of both experience and received wisdom. More important, he came to see that the progress of science came from a dialogue between the two. That in turn helped him realize that knowledge also came from a related dialogue: that between experiment and theory.”10

In building our knowledge, the environment we are in plays a huge part, as it is the source of our experiences. For this component, Leonardo was lucky, because he was born at a time and place that valued the mixing of ideas from different disciplines. In 15th century Florence there were others who brought multidisciplinary thinking to design and creativity. “This mixing of ideas from different disciplines became the norm as people of diverse talents intermingled. Silk makers worked with goldbeaters to create enchanted fashions. Architects and artists developed the science of perspective. Shops became studios. Merchants became financiers. Artisans became artists.”11 There is a role for discussion and communication in developing one’s knowledge. Sharing knowledge is a part of how you test it, seeing how much stronger your alloy really is after you’ve added some new information.

Imagination can drive curiosity, as was the case for Leonardo, and is an important component of the knowledge alloy. Imagining what can be drives you to validate what actually exists and then to apply the investigative rigor to see if you can bridge the two. Leonardo was exemplary in this respect. “His uncanny ability to engage in the dialogue between experience and theory made him a prime example of how acute observations, fantastic curiosity, experimental testing, a willingness to question dogma, and the ability to discern patterns across disciplines can lead to great leaps in human understanding.”12 We start with what we get in terms of genetics and environment, but at a certain point we take over control of what we can become. Understanding that knowledge is an alloy of experience and theory that can be further strengthened with elements of curiosity, imagination and sharing gives us the ability to develop it as a true source of power in our lives.

When to use it

  • Product development: combining market research (theory) with user testing (experience) to iterate a design.

  • Medical diagnosis: integrating textbook knowledge with clinical experience and attention to unique patient behaviors.

  • Educational curriculum: blending academic subjects with hands-on projects and real-world problem solving.

  • Personal growth: using psychological theories to understand patterns in your life and then testing new behaviors to see results.

FROM THEORY TO EVERYDAY LIFE

In practice

01

Driving a Car

When driving, we combine knowledge of road rules (theory), how to operate the vehicle (techne/craft), understanding of road conditions (experience), and anticipation of other drivers' behavior (phronesis/prudence). These knowledge components work together as an alloy.

02

Leonardo da Vinci’s Approach

Leonardo observed nature, hypothesized, and tested his ideas through further observation, bridging theory and experience. He also sought knowledge from others across disciplines, constantly strengthening his knowledge alloy.

03

Learning about a Hot Stove

Young children learn directly that a stove is hot (experience), but later learn the theory of heat production in a science class. Combining both leads to robust, transferable knowledge.

✳

A MOMENT TO REFLECT

Put it to work.

  1. What new knowledge could you gain by combining theoretical learning with direct experience in an area you're currently focused on?

  2. In what ways have you limited your understanding by relying too heavily on either theory or experience alone?

  3. How can you apply Leonardo da Vinci’s approach of observation, questioning, and cross-disciplinary exploration to a current challenge?
