But when your only +hammer is classical logic, every problem looks like modus ponens. In +contrast, computer scientists have invested considerable ingenuity in +studying tool design, and have made remarkable progress. + +"Why shouldn't I reinvent some idea X for myself? It's intellectually +rewarding!" Yes it is, but it also takes time you might have better +spent elsewhere. After all, you can get anywhere you want to go by walking, but you can +accomplish more with a combination of walking and strategic subway +rides. + +More importantly, the idiosyncrasies of your particular +implementation may obscure what's fundamental to the idea you're +working with. Your implementation may be buggy in corner cases you +didn't think of; it may be incomplete and not trivial to generalize; its +connection to existing literature and neighboring issues may go +unnoticed. For all these reasons you're better off understanding the +state of the art. + +The theoretical tools we'll be introducing aren't very familiar to +everyday programmers, but they are prominent in academic computer science, +especially in the fields of functional programming and type theory. + +Of necessity, this course will lay a lot of logical groundwork. But throughout +we'll be aiming to mix that groundwork with real cases +in our home subjects where these tools play central roles. Our aim for the +course is to enable you to make these tools your own; to have enough +understanding of them to recognize them in use, use them yourself at least +in simple ways, and to be able to read more about them when appropriate. + +Once we get up and running, the central focii of the course will be +**continuations**, **types**, and **monads**. One of the on-going themes will +concern evaluation order and issues about how computations (inferences, +derivations) unfold in (for instance) time. The key analytic technique is to +form a static, order-independent model of a dynamic process. We'll be +discussing this in much more detail as the course proceeds. -Sample content. +The logical systems we'll be looking at include: -More content added by git. +* the pure/untyped lambda calculus +* combinatorial logic +* the simply-typed lambda calculus +* polymorphic types with System F +* some discussion of dependent types +* if time permits, "indeterministic" or "preemptively parallel" computation and linear logic -Enabled "lockedit" plugin: testing that admins can still edit pages. + + + +## Who Can Participate? ## + +The course will not presume previous experience with programming. We +will, however, discuss concepts embodied in specific programming +languages, and we will encourage experimentation with running, +modifying, and writing computer programs. + +The course will not presume lots of mathematical or logical background, either. +However, it will demand a certain amount of comfort working with such material. +And it wouldn't be especially well-suited to be a first graduate-level course +in formal semantics or philosophy of language. If you have concerns about your +background, come discuss them with us. + +It hasn't yet been decided whether this course counts for satisfying the logic requirement for +Philosophy PhD students. + +Faculty and students from outside of NYU Linguistics and Philosophy are wlecome +to audit, to the extent that this coheres well with the needs of our local +students. + + +## Recommended Readings and Software ## + + *The Little Schemer, Fourth Edition*, by Daniel P.
