For readers, I will keep the content professional and output it according to numbers 1-20. 1. "Habit is the great guide of life." —— This sentence shows Hume's emphasis on habits and believes that habits play a key role in guiding people's lives. 2. "All reasoning can be divided into two categories, one is demonstrative reasoning, that is, reasoning about the relationship between ideas; the other is probable reasoning, that is, reasoning about the existence of actual things." —— Hume classified reasoning here, providing an important foundation for later philosophy and scientific methodology. 3. "When we focus on the object of investigation, the vivid idea that arises in the mind is impression." —— Hume's definition of impression emphasizes the intuitiveness and vividness of impression. 4. "All knowledge comes from experience, which is unquestionable." —— This sentence emphasizes the fundamental position of experience in the formation of knowledge, which is one of the core views of Hume's empiricist philosophy. 5. "All our simple ideas come from simple impressions when they first appear, which correspond to simple ideas and are accurately reproduced by simple ideas." - Hume expounds on the relationship between simple ideas and simple impressions, revealing the mechanism of idea formation. 6. "No image can convey any idea of its own existence through the properties presented to the senses." - This sentence challenges the traditional philosophical concept of perception and existence, and proposes the separation between objects and minds. 7. "Causal relationships are nothing more than habitual associations of our minds, not necessary connections in the objective world." - Hume's unique insights into causal relationships have had a profound impact on later philosophy and science. 8. "The self is just a bundle of perceptions or consciousness, which follow each other at an unimaginable speed and are in a state of eternal flow and movement." - This sentence shows Hume's profound insight into the fluidity and variability of self-consciousness. 9.

"All reasoning about facts seems to be based on causality, and causality is just a constant combination of objects that we observe through experience." - Hume expounded the empirical basis of causality here, providing a philosophical basis for the formation of scientific methods. 12. "All our reasoning about actual things seems to be based on a causal relationship, which is not based on reason, but only due to the constant combination of these objects we observe." - This sentence further emphasizes the irrational characteristics of causality and reveals the limitations of human cognition. 13. "Our knowledge does not exceed our experience." - This sentence concisely and clearly expresses the core view of Hume's empiricist philosophy. 14. "When we analyze our thoughts or ideas, no matter how complex or extended they are, we always find that they can be decomposed into simple ideas, which are originally derived from corresponding simple impressions." - Hume elaborated on the relationship between complex ideas and simple impressions here, revealing the process of knowledge construction. 15. "Moral distinctions cannot be obtained by reason. Reason, among all our concepts, cannot produce a concept related to justice or injustice, nor can it cause us to do anything except thinking about objects according to the natural relationship and connection between objects and ideas." - This paragraph explains Hume's views on morality and reason, believing that moral judgments do not come from reason, but from emotions and experience. 16.
