He was raised in
Lincoln, Nebraska, and earned his BA from the
University of Nebraska–Lincoln while studying under
Robert Audi. He earned his PhD from
Princeton University while studying under
Gilbert Harman, and was influenced by
Saul Kripke's work. His areas of concentration are
Analytic philosophy,
Philosophical logic,
Epistemology, and
Philosophy of Religion, and he is
conservative and
theist. In his first book,
Hume, Holism, and Miracles, Johnson purports to have refuted
David Hume's popular
argument for the irrationality of belief in testimony of miracles (as can be found in his essay entitled "
Of Miracles") as well as several reconstructions of Hume's argument, such as those of philosophers
Jordan Howard Sobel,
John Stuart Mill,
J. L. Mackie, and
Antony Flew. Subsequently,
Robert Fogelin (of
Dartmouth College) responded to Johnson's critique (among others') of Hume in his book
A Defense of Hume on Miracles, claiming that they had misunderstood Hume's argument.. Johnson's second book,
Truth Without Paradox, purports to resolve some traditional problems in
Metaphysics, including the
Liar paradox and the
Lottery paradox. In its fifth and final chapter, Johnson presents an
ontological argument and a historical argument for the existence of
God and the validity of the
Bible. ==Books==
