Albert Einstein (1879-1955).
'Elsbachs Buch: Kant und Einstein.' ?Offprint from: Deutsche Literaturzeitung 1 (1924): cols. 1685–1692. [Berlin: Walter de Gruyter, 20 September 1924].
Hans Albert Einstein’s copy of his father’s review of Alfred C. Elsbach's Kant und Einstein: Untersuchungen u?ber das Verha?ltnis der modernen Erkenntnistheorie zur Relativita?tstheorie ('Kant and Einstein. Analyses on the Relation between Modern Epistemology and Relativity Theory'). Published in 1924 by the same Berlin publisher of the Deutsche Literaturzeitung, Elsbach's book is critiqued even-handedly by Einstein. Einstein finds inconsistencies in Elsbach's rejection of the empirical theory of space, and his thoughts on the relation between logic systems and experiences. On the other hand, he accepts Elbach's admonishment of himself in relation to Einstein's assertion that a concept should only be permissible in physics when it can be established, regardless whether or not it applies in concrete cases of observation; Elsbach suggests that individual concepts must not only correspond with possible experiences, but also these concepts must correspond to a system as a whole. Einstein concludes: 'Elsbach’s book offers much neat and honest work of thought, and deserves to be studied by those interested in the relationship between philosophy and natural science.' Not in Schlipp nor Weil.
