" The common class of mankind are actuated by no nobler principle than that of self-interest; this and this alone determines all adventurers in privateers: the owners, as well as those whom they employ. "
- John Paul Jones

In simple terms, this statement suggests that people are primarily motivated by their own interests and benefits. According to the speaker, both the owners of privateer ships and those who work on them are driven solely by personal gain rather than noble or altruistic motives.

The deeper meaning of this quote reflects a broader skepticism about human nature and motivations in society. It implies that individuals often make choices based on what is most advantageous for themselves, even when these decisions may have negative consequences for others or the wider community. This view challenges idealized notions of selflessness and public service. Moreover, it raises questions about the reliability of people's actions and intentions in various contexts, such as business, politics, and social relationships.

The quote comes from John Paul Jones, a prominent naval figure during the American Revolutionary War. Known for his daring maritime strategies, he was also an influential voice on matters concerning maritime law and naval strategy. His perspective on human behavior often reflected his experiences at sea and in naval conflicts, where personal gain could be a strong motivator amidst the chaos of war.
