Step-by-step explanation:
David Hume believed reason was crucial for relations of ideas and scientific knowledge but held that moral knowledge and virtue were rooted in sentiments rather than pure reason.
Simply stated, David Hume's view on the role of reason in human life is that it has limited scope and cannot be the sole basis of moral knowledge or moral virtue. Hume distinguished between relations of ideas and facts about the world, noting that reason and logic can ascertain the former but have limitations when it comes to moral reasoning. Hume's skepticism led him to argue that while empirical evidence and rational thought are essential for scientific knowledge, moral judgments stem from human sentiments and passions rather than objective reasoning.
