"Even wisdom has to yield to self-interest"

This quote by Pindar suggests that even the most smart and experienced individuals can be swayed by their own self-interest. It indicates that when confronted with a choice, people may pick to act in their own best interest, even if it goes against their much better judgement. This might be interpreted as a warning against the risks of permitting one's own desires to override their knowledge.

The quote also recommends that wisdom is not always adequate to make the right decision. Even the most educated and knowledgeable individuals can be affected by their own self-interest. This could be viewed as a reminder to be familiar with our own inspirations and to be conscious of how they might affect our decisions.

Eventually, this quote acts as a tip that knowledge is not constantly adequate to make the ideal choice. We should know our own motivations and be mindful of how they may influence our choices. We must also be willing to accept our own self-interest when needed, even if it goes against our much better judgement.
