Summary
This quote highlights the power of independent thought and emphasizes that it is a resource that cannot be controlled or monetized. In a world where various aspects of life are subjected to taxation, such as income, goods, and services, thinking stands as an impenetrable realm of freedom and personal sovereignty. It suggests that one's ability to think critically and shape their ideas remains untouchable, reinforcing the notion that independent thinking is a valuable asset that cannot be quantified or regulated.
