The methods of logic are essential to an understanding of philosophy and are crucial in the study of mathematics, computing, linguistics and many other subjects. Introducing the major concepts and techniques involved in the study of logic, this authoritative book explores both formal and philosophical logic, and the ways in which we can achieve good reasoning. Individual chapters include: * Propositions and Arguments * Truth Tables * Trees * Conditionality * Natural Deduction * Predicates, Names and Quantifiers * Definite Descriptions. This exceptionally clear introduction to the subject is ideally suited to students taking introductory courses in logic.
But Bell has never had a challenge like this one. From Arizona to Colorado to the streets of San Francisco during its calamitous earthquake and fire, he pursues what is quickly becoming clear to him is the sharpest criminal mind he has ever encountered, and the woman who seems to hold the key to the bandit's identity. Using science, deduction, and intuition, Bell repeatedly draws near only to grasp at thin air, but at least he knows his pursuit is having an effect.
