"Knowledge is like money: to be of value it must circulate, and in circulating it can increase in quantity and, hopefully, in value"

In this quote, Louis L'Amour compares knowledge to cash, mentioning that in order for it to hold any worth, it needs to be shared and circulated. Similar to cash, knowledge has the prospective to increase in amount and worth when it is shared and utilized. The more it is flowed, the more it can grow and benefit others. This highlights the value of not hoarding understanding, but rather spreading it to others. By doing so, not only does the understanding become more valuable, but it also has the potential to favorably affect and benefit a bigger variety of individuals.
