He assists students by presenting easily remembered strategies for the clear application of the book's rules. His style encourages students' confidence both in understanding the issues involved and in their ability to work out complex problems.' - Thomas R. Foster, Ball State University 'Gensler's system is clear and straightforward. He presents his material in such a way that students feel encouraged as they grow their ability to perform logical operations... If ever a logic book deserved the attribute user-'friendly' then this is the one.' - Winifried Corduan, Taylor University
