Hastings Rashdall FBA (24 June 1858 – 9 February 1924) was an English philosopher, theologian, historian, and Anglican priest.

He expounded a theory known as ideal utilitarianism, and he was a major historian of the universities of the Middle Ages.

The dedication is appropriate, for the particular version of utilitarianism put forward by Rashdall owes elements to both Green and Sidgwick.

Rashdall has been eclipsed as a moral philosopher by G. E. Moore, who advocated similar views in his earlier work Principia Ethica (1903).

[15] He was president of the Aristotelian Society from 1904 to 1907,[16] a member of the Christian Social Union from its inception in 1890, and was an influential Anglican modernist theologian of the time, being appointed to a canonry in 1909.
