An Investigation of the Laws of Thought

"A classic of pure mathematics and symbolic logic ... the publisher is to be thanked for making it available." -- Scientific AmericanGeorge Boole was on of the greatest mathematicians of the 19th century, and one of the most influential thinkers of all time. Not only did he make important contributions to differential equations and calculus of finite differences, he also was the discoverer of invariants, and the founder of modern symbolic logic. According to Bertrand Russell, "Pure mathematics was discovered by George Boole in his work published in 1854."This work is the first extensive statement of the modern view that mathematics is a pure deductive science that can be applied to various situations. Boole first showed how classical logic could be treated with algebraic terminology and operations, and then proceeded to a general symbolic method of logical interference; he also attempted to devise a calculus of probabilities which could be applied to situations hitherto considered beyond investigation.The enormous range of this work can be seen from chapter headings: Nature and Design of This Work; Signs and Their Laws; Derivation of Laws; Division of Propositions; Principles of Symbolical Reasoning; Interpretation; Elimination; Reduction; Methods of Abbreviation; Conditions of a Perfect Method; Secondary Propositions; Methods in Secondary Propositions; Clarke and Spinoza; Analysis, Aristotelian Logic; Theory of Probabilities; General Method in Probabilities; Elementary Illustrations; Statistical Conditions; Problems on Causes; Probability of Judgments; Constitution of the Intellect. This last chapter, Constitution of the Intellect, is a very significant analysis of the psychology of discovery and scientific method.

How to download audiobooks from Youtube for free on the your iPhone & iPad.

After having many problems with the built-in audiobook player that comes with Apple products I was so happy to find this application. Not only does it accept MP3 files it joins them together. I have experienced numerous problems where an MP4 book will play in iTunes but would not play in the app that comes with my iPhone. This application plays them all flawlessly. And the increased speed is perfect. As one who consumes 2 to 3 audiobooks a week this is just what I needed.

This app has a ton of features for listening to your audiobooks. The shake to extend the sleep timer is very convenient and a feature I miss when I switch back to the Audible app for my library there. Also, the equalizer has been a really nice addition along with the audio preset built in. I can keep my books out on my iCloud Drive and download them when I’m ready to listen. Great app!

The app allows a lot of freedom as far as organization and playback speed. Sleep timer is adjustable and combining books into series folders is simple. Equalizer helps to adjust pitch when playing at high speeds and helps reduces feedback with poor quality recordings. App never crashes and I don’t have any complaints.

Fits the bill perfectly to play audiobooks ripped from other media: premium version allows bookmarking, reading rate change (the best I've ever seen from .5x through 3x and every variation in between) and sleep timer. Plays files in multiple formats, including mp3s and m4b (audiobook version of m4a). Easy to load books through iTunes file sharing. I haven't tried the wireless method. Well worth the money for the premium version (which you can just purchase outright, but I got it free first, liked it, and almost immediately did the IAP for the pro features). Been looking for a solution since Audible discontinued the feature to play your own iTunes audiobook library and iBooks is inadequate. This is it. Highly recommended. Found this while trying to figure out how to play a library of audiobooks from a favorite author ripped from cassettes and CDs (not available on Audible - always my go-to).
