The boldness of Powell and other theologians in dealing with science led Joseph Dalton Hooker to comment in a letter to Asa Gray dated 29 March 1857: "These parsons are so in the habit of dealing with the abstractions of doctrines as if there was no difficulty about them whatever, so confident, from the practice of having the talk all to themselves for an hour at least every week with no one to gainsay a syllable they utter, be it ever so loose or bad, that they gallop over the course when their field is Botany or Geology as if we were in the pews and they in the pulpit. Witness the self-confident style of Whewell and Baden Powell, Sedgwick and Buckland." William Whewell, Adam Sedgwick and William Buckland opposed evolutionary ideas.Huxley, Leonard 1918.
