"understanding without action leads to nothing being done in the end". Sounds like "Shoot first and ask questions later" (a philosophy I ascribe to myself)
This all sounds very much like Kant's Transcendental Aesthetic... another attempt at the great epistemological question.
Well not really shoot first, you missed the part of understanding being about WHY, and the knwoeldge being about WHO, WHAT, WHERE, WHEN. Questions first :P
But from what I gathered, it talked about understanding being intuitive... an a priori understanding... shoot first and... was just a sort of crude generalization of that.
