This work is an excellent and easily accessible resource material, especially for those interested to pursue further studies in advanced logic. It is a roadmap that tells you how to navigate your way in the forest of different logical theories. It serves as a gateway to the "plurality of logics". Jeremiah Joven Joaquin, De La Salle University, Manila.

With this new edition, Logic the basics is the best introductory textbook for non-classical logic. It clearly introduces each new topic and shows how it connects to earlier chapters. It is a fantastic choice for introducing undergraduates to exciting developments in logic. Tracy Lupher, Co-director of the Logic and Reasoning Institute, James Madison University, USA
