# Software and Tutorials for Instruction in Symbolic Logic

###### 2/1/2020

## Welcome

*This site contains software and instruction for symbolic logic. The content is relevant mainly to philosophy, mathematics, or computer science. Most of the material is at about a level suitable for entire courses for second year undergraduates, or for sections of graduate courses. [Indeed it has been used for instruction in the University of Otago, New Zealand, the University of Arizona, in the US, and elsewhere.] **The software on this site should run quickly on any modern computers, tablets, and smartphones (iPads, iPhones, Android tablets, etc.).*

*Enjoy!*

## New material

- Some new Source Code (2/1/2020)

- Tree Tutorials [Propositional, Predicate, Identity, and Modal Logic Trees—Default Syntax]

## eBooks available from iTunes and the iBookstore

*These will run directly on suitable devices (e.g. iPads) without need for a web browser or an internet connection.*

*[These, and the software, can be configured to accompany almost any text-- send us an email.]*

## Legacy pages

*Many of the old pages contain java applets, these can take 20-30 seconds to load initially (so you may find yourself looking briefly at a blank page when opening some material). There are only a few of these pages that are left. Viewing java applets through a web browser is not easy these days, but if you try it you **might also want to look at Checking Your Computer is Configured Correctly.*
