In the tree-like representation of Time, two historiesare ’’undivided‘‘ at a moment t whenever they share a commonmoment in the future of t. In the present paper, it will first be proved that Ockhamist and Peircean branching-timelogics are unable to express some important sentences inwhich the notion of undividedness is involved. Then, a newsemantics for branching-time logic will be presented. The new semantics is based on trees endowed with an ’’indistinguishability‘‘ function, a generalization of the notion of undividedness. It will be shown that Ockhamist and Peircean semantics can be viewed as limit cases of the semantics developed in this paper.
