Id William James do more to help, or hurt, the cause of religious faith in the 20th century?

The only source that should be used is William James Varieties of Religious Experience: A Study in Human Nature.”

Please make the argument that James did more to HELP the cause of religion. Here are some arguments that should be included:
-science has gained tremendous social prestige
-James used to science to show that religion was the major factor in producing human happiness
-he furthered the study of psychology which could not prove the nonexistence of God
-he helped religion in secular places (universities & science)
-his argument is flawed in hindsight, but he saved religion in the face of Darwinism and the New sciencewhen no one else was able to

if theres any way possible I really need this by noon on Friday
