Introduction

The logic of Aristotle underlies the modern digital computer. Logical rules developed to analyze the truth of verbal arguments led eventually to symbolic logic where true and false become 1 and 0, respectively, following the work of Claude Shannon in the last century. Symbolic (or propositional) logic can be used to formulate algebraic operations. The final steps, exemplified by the electronic computer, were to convert true and false values to voltages and logical operations to simple circuits, simple circuits that can be combined in the millions to produce a computer.
