`Englebretsen and Sayward's book fills a gap in the current array of logic textbooks available. It starts from the beginning, thus allowing students to gain the first rudiments of symbolization; yet, it covers areas usually neglected in introductory logic textbooks such as set theory and modal logic. Finally, it presents a constructivist approach in contrast to the point of view of classical logic usually tacitly assumed in logic textbooks and a substitutional rather than an objectual interpretation of quantification. This is truly a logic textbook for philosophers.'
