Abstract: Modern logicians ordinarily do not distinguish between the terms hypothetical and conditional. Yet in the late nineteenth century their meanings were quite different and their tie to implication unclear. In this paper, Francine Abeles will explore the views of four prominent British logicians of the period, W. E. Johnson, J.N. Keynes, H. MacColl, and J. Venn on these issues.
