About this quote
This page records the wording "But without deeper reflection one knows from daily life that…," which centers on without, deeper, reflection. A concrete trail points toward Einstein, but the exact English form remains unconfirmed; the page therefore labels it as attributed to him while preserving its happiness and life context.
When to use it
- Use "But without deeper reflection one knows from daily life that…" in a happiness discussion, then ask which concrete claim the wording makes.
- Compare its treatment of without with deeper in a lesson, essay, or editorial note before drawing a conclusion.
- Before sharing it as Einstein's exact words, display the attribution caveat and follow the evidence link recorded on the page.
