+<h2>What is  Isabelle?</h2>
 Isabelle can be viewed from two main perspectives.  On the one hand it
 may serve as a generic framework for rapid prototyping of deductive
-systems.  On the other hand, major object logics like
+systems.  On the other hand, major existing logics like
 <strong>Isabelle/HOL</strong> provide a theorem proving environment
 ready to use for sizable applications.
