The problems in ontology and the philosophy of logic on which Karel Lambert works are not new. They date from the very beginnings of Western philosophy. But his work provides original solutions to several of them, and in the process illuminates the history of their development. Much of my own work, in fact, has simply involved applying Lambert's results to 17th and 18th century texts.
