Final answer:
The justified generalization from the paragraph is that the author believes an individual can make a lasting difference in the world, primarily due to the distinct human capacities for reason and influence.
Step-by-step explanation:
The paragraph from the question discusses the ephemeral impact of animals like tigers compared to the lasting legacy humans can leave through their actions, decisions, and the influence they have on others. It emphasizes the unique human ability to reason and exert influence beyond their lifetime, in contrast to animals whose actions are primarily governed by instinct and the laws of nature.
The generalization that can be drawn from the given paragraph is that the author believes one person can make a difference in the world. This idea is reflective of the human ability to carry out actions that have long-lasting impacts, often shaped by moral reasoning, conscience, and reflection on one's life. It is clear from the text that tigers, despite their majesty, do not impact the world in a way that outlasts their death, whereas humans have the capacity to influence the world and future generations.
This concept is supported by the provided references that discuss the qualities that define humanity, including the use of reason, moral development through reflection, and the ability to extend compassion from the self to the broader community. Overall, man's ability to influence and make a difference is a shared theme across these references.
