"For while the subjects of poetry are few and recurrent, the moods of man are infinitely various and unstable. It is the same in all arts"

This quote by John Drinkwater talks to the idea that although the subjects of poetry are limited, the emotions and sensations of individuals are large and ever-changing. This principle can be applied to all types of art, not just poetry. Drinkwater is suggesting that although the subjects of art might be restricted, the emotions and feelings that are expressed through art are endless. He is emphasizing the significance of emotion in art, and how it can be used to communicate a wide variety of feelings and concepts. He is likewise suggesting that the exact same subjects can be explored in different ways, depending on the artist's emotional state. This quote speaks to the concept that art is a powerful tool for revealing emotion, which it can be utilized to explore a vast array of topics.
