THE FIELD EQUATIONS OF GRAVITATION 26l
ing me. It is really a shame if two real fellows who have freed themselves to some
extent from this shabby world should not enjoy each other' [E60]. The full story
may never be known. However, in a reply to a query, E. G. Straus wrote to me,
'Einstein felt that Hilbert had, perhaps unwittingly, plagiarized Einstein's
[largely wrong!] ideas given in a colloquium talk at Goettingen.* The way Ein-
stein told it, Hilbert sent a written apology in which he said that '[this talk] had
completely slipped his mind.. ." [SI]. Whatever happened, Einstein and Hilbert
survived. The tone of their subsequent correspondence is friendly. In May 1916
Einstein gave a colloquium on Hilbert's work in Berlin [E61]. On that occasion
he must have expressed himself critically about Hilbert's approach.** In May
1917 he told a student from Goettingen, 'It is too great an audacity to draw
already now a picture of the world, since there are still so many things which we
cannot yet remotely anticipate' [S6], an obvious reference to Hilbert's hopes for a
unification of gravitation and electromagnetism. Einstein was thirty-eight when
he said that. He was to begin his own program for a picture of the world shortly
thereafter. ...
