We may know a paternal aunt and a niece who has a _ paternal aunt, but that does not mean that these two friends of ours are related in this way to each other. Sometimes, we can deduce this, and then the relation is said to be con- nected. Symbolically, we may say that a relation is con- nected when, given any two terms, x and y, in its field, then either xRy or yRx. LOGIC byE. C. Tubb We have now more or less covered the groundwork of deductive logic. True, we have barely touched upon the various topics, and have avoided as far as possible the controversial points.

Next month we shall move on to the absorbing topic of scientific method—inductive logic—and deal with such interesting subjects as causa- tion and hypotheses; matters which form the backbone of experimental science. is next month’s feature novel. Other stories include Forgive Them by Dan Morgan, Asteroid Crusoe by Jonathan Burke, Insomnia Cure by E. Everett Evans, The Jar of Latakia by Edmund Cooper, and Science Fiction Story by Richard Wilson. All the usual non- fiction features. AUTHENTIC—A MONTHLY MUST! 95 comicloooks.com
