Introduction. This paper is an elaboration of the talk I gave at the American Mathematical Society meeting held at Memphis State University in November, 1977. In that talk I tried to illustrate what was special about four-dimensional topology and mention some of the advances in that subject. I have expanded upon that talk somewhat in this paper in order to give a clearer picture of the geometric ideas and methods currently used in studying four-dimensional manifolds.
