Science, it cannot be too often repeated, deals with tangible phenomena. The man of science like the man in the street has to face hardheaded facts that cannot be blinked and explain them as best he can.

Context

“It had better be stated here and now at the outset that the perverted transcendentalism to which Mr S. Dedalus’ (Div. Scep.) contentions would appear to prove him pretty badly addicted runs directly counter to accepted scientific methods. Science, it cannot be too often repeated, deals with tangible phenomena. The man of science like the man in the street has to face hardheaded facts that cannot be blinked and explain them as best he can. There may be, it is true, some questions which science cannot answer—at present—such as the first problem submitted by Mr L. Bloom (Pubb. Canv.) regarding the future determination of sex. Must we accept the view of Empedocles of Trinacria that the right ovary (the postmenstrual period, assert others) is responsible for the birth of males or are the too long neglected spermatozoa or nemasperms the differentiating factors or is it, as most embryologists incline to opine, such as Culpepper, Spallanzani, Blumenbach, Lusk, Hertwig, Leopold and Valenti, a mixture of both?” source
