"Another scintillating collection of brilliant problems and paradoxes by the most entertaining logician and set theorist who ever lived." -- Martin Gardner"Smullyan is not your run-of-the-mill puzzlemeister; he polishes up old chestnuts, spins variations on a theme, and peoples his logical world with a delightful cast of characters." -- Science 82
"I believe Ray Smullyan to be the Lewis Carroll of our times. His little books of logic puzzles will be remembered long after most of us are forgotten." -- Peter Denning, Chairman of the Computer Science Department, Naval Postgraduate School
"You may experience small frissons of delight as you follow Smullyan into the dizzying heights of G del's proof and the very nature of proof, truth, and logic in mathematics." -- Kirkus Reviews
Discover scintillating new perspectives on the principles of mathematical logic with this puzzle treasury. Inspired by the classic tale of a prisoner's choice between two doors, these whimsically themed challenges allow readers to base their decisions on logic rather than luck. Nineteen chapters advance from relatively simple puzzles and meta-puzzles to highly complex paradoxes involving probability, time, and change. The author, a well-known philosopher and magician as well as a celebrated mathematician and logician, was acclaimed by The New York Times as "a master at translating difficult ideas into stories and puzzles that require no formal background, only patience and a passion to learn."

Great product
Color: Camouflage, Color: Camouflage
I bought these bags for my 2022 CanAm Outlander. They are a hair too short to use the buckles on the front fender but fit like a dream on the back fender. They do have the Velcro option in the back but I don’t want to stick anything to my bike. They sit perfectly flat though so I foresee NO problems :)
They are a quality material and hold everything I will need. I am very happy with my purchase!

Held up well first season in rain and snow, compartments a little shallow
Color: Camouflage
Overall these are a good product. The fit was good on my 2014 Honda Rancher AT, and they stay put when riding. I have left it out in rain and snow, and the contents stay dry so far. They seem pretty durable, but a few seasons exposed to sun and hot/cold will show for sure.
The detachable "purse" pouch is kind of cheesy. Not sure I would ever need that feature. THe other pockets are fine for keeping things separated and out of the elements. I think if you put heavy metal items like a hammer and nails in there it would wear through it. But good for everyday stuff like gloves and keys and cell phones and water bottles.
The other thing that seemed a little off was the depth of the pockets. When new the zipper openings are hard to spread apart, and inside you can't put anything very bulky unless it compresses easy like a fleece coat or gloves. So you would still need a rack bag for bulkier items.
For me it does the job of keeping odds and ends accessible and not left on the trail someplace.

Decent product!
Color: Camouflage, Color: Camouflage
Just put it on today. Put my phone and wallet in the top pockets. Took a ride up through the back of my property and didn't lose anything. Can't complain but time will tell. You guy's are lucky I didn't give you 1 star for the annoying reminders of a review before I used the product.
