The Ultimate Quotable Einstein, edited by Alice Calaprice (Princeton University Press, 2010), p. 474.
Editorial Note
Our review of scholarly quotation collections reveals that this sentiment appears in Alice Calaprice's definitive work on Einstein, where it is traced to a 1955 *LIFE* magazine interview. While we conducted broad searches through the collected papers and standard archives without locating the verbatim text directly there, Calaprice serves as our primary authority because she explicitly identified the specific periodical source at that time. We found no credible evidence of an alternative originator or a documented instance where this phrasing predates Einstein's era to suggest misattribution, nor is there any serious academic dispute challenging his authorship other than minor textual variations across internet aggregators. The absence of a direct digital match in search engines does not negate the scholarly attribution found by Calaprice within her curated volume, which distinguishes it from unverified web folklore. On the evidence available and the reliance on this reputable secondary verification source that points to a contemporary interview, we are marking this quotation as verified.
