"Happy the man who has been able to learn the causes of things"

In this quote, Virgil is highlighting the worth of knowledge and understanding. He recommends that a person who has had the ability to uncover the source of things is in a lucky position. This is because by understanding the underlying reasons for occasions or phenomena, they can better navigate the world around them, make more informed decisions, and potentially even influence results in their favor. Virgil's declaration can likewise be translated as a call to action - a support to seek out understanding and explore the factors behind what we see and experience, instead of just accepting things on surface level.
