“All knowledge of reality starts from experience and ends in it. Propositions arrived at by purely logical means are completely empty as regards reality. Because Galileo saw this, and particularly because he drummed it into the scientific world, he is the father of modern physics – indeed, of modern science altogether.”

About this quote
This source-reviewed Einstein quotation develops a complete idea around knowledge, reality, starts. The wording "All knowledge of reality starts from experience and ends in…" is tied to "On the Method of Theoretical Physics" (1934) from Einstein's essays in science. Translat…, so readers can connect its themes of science and education to a documented context rather than a detached slogan.
When to use it
- Use "All knowledge of reality starts from experience and ends in…" in a science discussion, then ask which concrete claim the wording makes.
- Compare its treatment of knowledge with reality in a lesson, essay, or editorial note before drawing a conclusion.
- When publishing or narrating it, retain the documented source trail to "On the Method of Theoretical Physics" (1934) from Einstein's essays in science. Translat… so the quotation stays connected to its original context.
