He discovered the truths that led to the equation E=MC2 and the theory of relativity by conducting visual thought experiments. Famously, he imagined riding alongside a beam of light.
Pestalozzi’s motto was “Learning by head, hand and heart”. He wrote that “Visual understanding is the essential and only true means of teaching how to judge things correctly.” The learning of numbers must be subordinated to first understanding concepts, he believed.
On so many levels, our worldwide community of Color Accounting educators are proud to call ourselves “Pestalozzians”. Belief in the individual. Use of hands in the learning process. The power of the visual BaSIS Framework we use. And even the priority of words over numbers as one learns to make sense of financial statements.
200 years later we are unreservedly happy to take our hats off to you, Johann Heinrich Pestalozzi, with a deference you wouldn’t demand from us.
