In "The Dialogue of the Dogs," Miguel de Cervantes Saavedra explores the nature of generosity and giving. The quote suggests that true generosity comes from the heart rather than material wealth. Those who are truly kind will share what they can, even if they have little to give, while those who are greedy may hold back despite their wealth.
I find the saying "The hard-hearted give more than the poor" to be misguided. It implies that a selfish person could ever genuinely offer anything of value. In contrast, a poor but generous person can still provide hope and goodwill, which are significant contributions despite their lack of material resources.
