It made no sense, he said, to speak of time as having an absolute existence that was independent of observable objects whose movements permitted us to define time. “From the succession of ideas and impressions we form the idea of time,” Hume wrote. “It is not possible for time alone ever to make its appearance.” This idea that there is no such thing as absolute time would later echo in Einstein’s theory of relativity. Hume’s specific thoughts about time, however, had less influence on Einstein than his more general insight that it is dangerous to talk about concepts that are not definable by perceptions and observations.”” [Walter Isaacson](https://sms4smile.com/quotes/author/walter-isaacson/) ## About This Quote This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation. Hume argues that time is a mental construct derived from observed changes, not an independent entity. **In simple terms:** Time is a concept built from what we see change. Key Takeaway Recognize that many ideas depend on perception. Themes philosophy epistemology science Mood analytical thoughtful Type philosophical educational When to use this quote - physics discussions - philosophical debates - educational curricula - science communication Key Concepts perception relativity conceptual analysis Questions to Reflect On - How do we measure time without assuming its existence? - Can we think of other concepts similarly? A Different Perspective Time may be useful even if not absolute, limiting practical applications. ★ ★ ★ ★ ★ No ratings yet [Clock](https://sms4smile.com/quotes/about/clock/) [Concept of time](https://sms4smile.com/quotes/about/concept-of-time/) [Time](https://sms4smile.com/quotes/about/time/) [Time alone](https://sms4smile.com/quotes/about/time-alone/) ## Related quotes > [There is a time for the maturing of thoughts such as there is a time for the maturing of wheat, of wine, of stars...](https://sms4smile.com/quotes/mariana-fulger/there-is-a-time-for-the-maturing-of-thoughts-such-as-there-is-a-time/) [Mariana Fulger](https://sms4smile.com/quotes/author/mariana-fulger/) > [I would say I had zero philosophical thoughts at that time.
