Foundations Without Foundationalism, A Case for Second-Order Logic

Creator: Stewart Shapiro | Mathematics - 2000-05-18

Foundations without Foundationalism is a key contribution both to philosophy of mathematics and to mathematical logic. 'In this excellent treatise Shapiro defends the use of second-order languages and logic as framework for mathematics.

Publisher: Oxford University Press, USA

About this book
Stewart Shapiro presents a distinctive and persuasive view of the foundations of mathematics, arguing controversially that second-order logic has a central role to play in laying these foundations. To support this contention, he first gives a detailed development of second-order andhigher-order logic, in a way that will be accessible to graduate students. He then demonstrates that second-order notions are prevalent in mathematics as practised, and that higher-order logic is needed to codify many contemporary mathematical concepts. Throughout, he emphasizes philosophical andhistorical issues that the subject raises. Foundations without Foundationalism is a key contribution both to philosophy of mathematics and to mathematical logic. 'In this excellent treatise Shapiro defends the use of second-order languages and logic as framework for mathematics. His coverage of the wide range of logical and philosophical topics required for understanding the controversy over second-order logic is thorough, clear, and persuasive. . . .Shapiro recognizes that it is unlikely that he has had the last word on these controversial philosophical subjects. Nevertheless, his book is certainly an excellent place to start work on them.' Michael D. Resnik, History and Philosophy of Logic

    Dependable, solid, large

    This Case-Logic CD carrier is a good, solid storage device. It is pretty standard wallet, with space for 208 CDs or DVDs divided into 26 pages of sleeves (4 CDs each side, front and back), plus space for an additional 16 CDs inside the front cover. Although it is a tight squeeze, it is possible to fit both the CD and the booklet or liner notes into the same sleeve. The pages are held in place in a ring-binder type arrangement, so it is possible to unlock them and take individual pages out of the case, if you want to remove them for travel (or possibly to add more pages for more storage.)The sleeves are well padded, so your discs shouldn't get scratched. The top, bottom, and binding of the case are solid, and leave the contents well protected. I've had my case a few months and haven't had any significant wear or tear- the zipper seems to hold up well, too.Obviously, when full of 200+ discs, the case can get pretty heavy, and isnt going to be something that you want to... 5/5 D.

    Great solution to CD Storage -- get rid of your jewel cases!

    It is wonderful grabbing one of these cases and flipping thru the pages to find my CDs, rather than pawing thru jewel cases, knocking over the stacks of them, and giving up after a half hour of searching. I have 3 CDW-320's, each holding a different genre of music. In a fire, I could grab all three cases and go, where that would've been impossible before. By my calculations, the physical space used by my CD collection has decreased by 40%!The way to do what I did is to get rid of the jewel cases entirely. To do that, do this for each CD you own:1) Each side of each CDW-320 page has four pockets. Put the CD in one of the two top-most Pockets on a page.2) Put the CD's booklet in the pocket underneath its CD.3) Finally, pop open the CD case (it takes just a little force) and pry out the back-of-the-CD card. Straighten out the folds of that card, and slide it in sideways into the bottom pocket, behind the CD's booklet. It will... 5/5 W. L.

    A first rate product

    Like the other Case Logic CDW wallets, this one has removalbe pages, holds the discs securely, and has room for rather substantial liner notes. Those that won't fit in the sleeves will fit in the pockets up front.Because of the unique design of the locking system however, inserting papges is not particularly easy -- the rings lock in front of the first page, so to insert a page, you have to pull out all of the pages in front of it. It would have made more sense to have it lock in the back -- that is where you would either want to add pages, or remove the extra ones.All in all, we are pleased ... it is a great way to store our cd's, it gets rid of that major shelving system we bought only for our discs, and, frankly, the discs are more accessible, than in some of those fancy jewell cases.My favorite aspect of the wallets is that we actually listen to our music more -- we were storing our discs in our library -- away from our stereo, so you actually... 4/5 bob - See all my reviews Verified Purchase(What's this?)

    Durable, high quality CD wallet

    Let's start with the outside of the wallet. The design is elegant, and minimalistic, with a slight curve down the left front side, also serving as a handgrip, and a line through the middle, along with the Case Logic logo. The zipper has a rubber tab attached to it, and it zips open and closed without any hassles. The entire wallet has a very durable feel to it.Inside, each page lets you store two CDs, or a single CD, plus notes/game manuals. Pages flip easily, and discs seem easily to slide in and out as well, at least compared to the Velocity CD wallets which were recently on sale here at Amazon with rebates.Zipping the wallet up, turning it upside down, and banging on it, one finds that the discs stay in place, and don't slide towards the top, again, unlike the Velocity CD wallets where discs often slides towards the top just while turning pages.All in all, this is a very well thought-out CD wallet, with a nice design, and seemingly durable... 5/5 Phillip Roncoroni "goodcowfilms.com" (Manhattan, New York) - See all my reviews, September 5, 2005

    It Will Survive A War...And Then Some (Seriously)

    I've been a fan of Case Logic wallets for years; I'm generally a very active person who hauls his disks around for trips both short and long. I've owned some Caselogic wallets for 8+ years without ever having to replace it.Such is the situation for this Case Logic wallet. I've carried it around with me in Iraq for six months now, and it generally lives to its standards. Solid and crush-resistant, very durable, the only problem I've had with it is its tendency for one or two of the plastic disc holders have ripped. But such is the case with such heavy wear/tear. If you're like me, storing both album art and CD in the same sleeve, it's what you need. It also has a side pocket on the inside front cover for me to store back inserts and/or miscellaneous excess DVD/CD material that comes with the packaging.Buy this if you're mobile; buy it if friends tend to step on your case; buy this if through no fault of your own your cases are constantly abused.

    Good lightweight briefcase to hold both a 15-inch laptop and my iPad 2, but may be too slim if your AC adapter brick is thick.

    இ Fuzzy Wuzzy's Summary:ѾѾѾѾ Recommended with warm fuzzies (but the slim interior space is better suited either for a laptop with a compact slim AC adapter, or an 11-inch or 13-inch ultrabook or MacBook Air).The first thing that I noticed about this laptop briefcase was how light and slim it was. This briefcase only weighs 21 ounces (1 pound 5 ounces), including the shoulder strap, which is lighter than many laptop bags. The exterior feels like soft neoprene while all interiors are lined with nylon. The main laptop compartment has dimensions of 15.25 inches wide and 11.25 inches deep, and can accomodate a laptop of 15.2"x10.5"x1.7". Inside the main laptop compartment is an 8.0-inch wide sleeve that perfectly fits my iPad 2. My iPad 2 is covered with the excellent ... 4/5 ƒůŽźŸ ωŬ&#... - See all my reviews, January 8, 2012

    Nice, but be sure this is what you want ...

    Please note, there are 4 sizes (10, 10.2, 14, and 16 inches) of the same case type; I am writing a review of the 16-inch case.This is a well-made but relatively inexpensive bag for a laptop PC. It is so light that I can barely feel its weight, but it still has sufficient padding to protect its contents against bumps during everyday use.This is NOT the kind of case with zippers that can be pulled further to the left and right sides when you open the bag. In other words, the opening for you to put in and take out things is very small. Does this matter? Yes, if you have a laptop PC that measures diagonally 15.6 to 16 inches. The fit is snug, and because of the narrow opening, putting in and taking out a computer is not that smooth and easy. Although the zippers are plastic, there is a chance of them scraping against the computer's edges. I would not recommend this case if you have concerns about this aspect. If your computer is a netbook, which is about 10 inches... 3/5 Amazonian Consumer - See all my reviews, March 22, 2010

    This laptop bag is very well padded inside that I almost wanted this bad formy cameras. The design looks very simple, yet the interior pockets andpadding are very well made. Because of its cloth material, it feels littlebit cheap, but then again it is very light. There is also enough room fortwo laptops, maybe one 13 inch Mac book Pro and a 10 inch Net book, with allthe power blocks in the front pocket. There is an additional small pocketfor a cell phone or other small accessories, and I liked this pocket a lotbecause it is easy to reach, not to mention its location is convenient. Icould not find any cons about this bag, not only because it comes with ashoulder strap, but also because it has a "25 Years Quality Guarantee"stamp.
