This course provides an introduction to the aims and techniques of formal logic. Logic is the science of correct argument, and our study of logic will aim to understand what makes a correct argument good, that is, what is it about the structure of a correct argument that guarantees that, if the premises are all true, the conclusion will be true as well? Our subject (though, to be sure, we can only scratch the surface) will be truth and proof, and the connection between them.
