Final answer:
The assertion that David Hume's concept of 'impressions' refers to vague intuitive hunches is false. Impressions are direct sensory experiences and the basis of his empirical approach to the acquisition of knowledge.
Step-by-step explanation:
When David Hume refers to "impressions," by this he means the vivid sensory experiences and emotions that are present in our awareness, rather than vague, intuitive hunches. This statement about impressions being vague, intuitive hunches is False. Impressions, according to Hume, are direct, forceful entries in the mind that come from sensory experiences. They are the building blocks from which ideas are formed, which are less vivid and more derivative. Hume's philosophy emphasizes that all ideas are ultimately derived from the initial impressions that we experience through our senses. Furthermore, Hume argued that empirical observation is the primary source of knowledge and that reasoning alone, a priori, does not lead to knowledge. This focus on sensory experience is part of Hume's larger philosophical approach called empiricism, which posits that knowledge originates in experience.
