This well-organized book was designed to introduce students to a way of thinking that encourages precision and accuracy. As the text for a course in modern logic, it familiarizes readers with a complete theory of logical inference and its specific applications to mathematics and the empirical sciences.Part I deals with formal principles of inference and definition, including a detailed attempt to relate the formal theory of inference to the standard informal proofs common throughout mathematics. An in-depth exploration of elementary intuitive set theory constitutes Part II, with separate chapters on sets, relations, and functions. The final section deals with the set-theoretical foundations of the axiomatic method and contains, in both the discussion and exercises, numerous examples of axiomatically formulated theories. Topics range from the theory of groups and the algebra of the real numbers to elementary probability theory, classical particle mechanics, and the theory of measurement of sensation intensities.
Ideally suited for undergraduate courses, this text requires no background in mathematics or philosophy.

So much fun
Style: Flying Glow Squirrel
My shepherd loves this thing. He is a true fiend for a frisbee or ball and this is his new favorite toy. He will carry it around just to do so, and that’s a new thing for him. It’s soft which is good for my poor hands, yet it’s durable and stands up to the tests he throws at it. It flies well and hasn’t warped no matter what it’s hit. No tears through any of the chewing yet either. Good size toy that gives hours and hours of fun for the most playful and silly doggos out there!

Beloved dog toy now in glow in the dark canvas.
Style: Flying Glow Squirrel
This is a great frisbie style product with the advantage of glow in the dark visibility. My German Shepherd has been retrieving the original Chuckits for 5 years. They fly through the air and have the advantage of curved design which allows a dog to slide their mouth under it easily when it is on the ground. Awesome dog toy that my dog never tires of. Heavy duty canvas design for durability and washability when it gets muddy.

Great, tough, and will not break your dog’s teeth!
Style: Giggle Fumble
I am the aunt of several different types of dogs and they all love the giggle toys. The problem with most of them is that they are hard to Plastic (I guess so the dog doesn’t bite into the giggle box and disable it). Every pup I know is crazy about the giggle toys, but I’m always afraid they’ll break teeth. This one is very tough material but not hard so that your dog could bite down on it and enjoy the giggle.

Perfect for strong chewers!
Style: EcoFetch
Best balls for dogs who love to tear up toys. My pup tore up regular tennis balls but he can’t tear these up and he loves to just chew them. Will always buy these for our fur baby!

Beagle’s Best Friend
Style: Super Crunch Stick, Style: Super Crunch Stick
This is my dog’s favorite toy! We’ve had it for about 6 months now. She plays with it and chews on it every single day. She takes it everywhere. Despite all her rough housing with it, it is still completely intact, so it is extremely durable! Love this thing! We call it her “crunchy carrot”
