defense system that has evolved to protect animals from invading pathogenic microorganisms and ancer. It is able to generate an enormous variety of cells and molecules capable of specifically recognizing and eliminat ing an apparently limitless variety of foreign invaders. These cells and molecules act together in a dynamic network whose omplexity rivals that of the nervous system. Functionally, an immune response can be divided into two related activities--recognition and response. Immune

Grammar is the structural system of a language. The grammar of English is organized into five ranks: the sentence, the clause, the phrase, the word and the morpheme. Each rank is composed of one or more than one grammatical unit of the immediate lower unit. A full sentence can generally be segmented rank by rank down to its smallest constituents---the morphemes

Optimal Routing View routing as\global\ optimization problem Assumptions: The cost of using a link is a function of the flow on that link The total network cost is the sum of the link costs The required traffic rate between each source-destination pair is known in advance Traffic between source-destination pair can be split along multiple paths with infinite precision

Data Link Layer (DLC) Responsible for reliable transmission of packets over a link Framing: Determine the start and end of packets(sec 2.5) Error Detection: Determine when a packet contains errors ( sec 2.3) Error recovery: Retransmission of packets containing errors(sec 2. 4) DLC layer recovery May be done at higher layer

October 22, 2001 Personal IdentityⅢ . Review soul criterion and body criterion Soul criterion: x is the same person as y iff and y have the same soul. Problems: i)There is no way to establish body-soul correlations; and no way to establish personality correlations. So soul criterion doesn't make sense of our practices of recognizing and identifying people ii)We have no special access to souls, so even in our own case we can't be sure it's the same soul \inside\ us whenever we are conscious. ii) The problem of identity is \pushed back\: what is it for person-stage x to have the same soul as person-stage y? What makes for sameness of souls? Body criterion: x is the same person as y iff x and y have the same living human body

24.00: Problems of Philosophy Prof. Sally Haslanger November 7, 2001 Freewill IlI: Libertarianism I. Recap: Compatibilism v. Incompatibilism Hard determinism is the view that determinis is true and that because of this freedom is an illusion. The libertarian agrees with the hard determinist that freewill is incompatible with determinism, but disagrees about which claim should be rejected. The libertarian holds that we have free will, but this is only because determinism is false-free acts occur and are undetermined. The hard determinist and the libertarian are both incompatibilists. Soft determinism, also known as compatibilism, maintains that determinism is true, but also that determinism is

Evidentialism(Clifford): \It is wrong abways, everywhere, and for anyone, to believe anything upon insufficient evidence\ (p.113) Pragmatism(James): Faced with a genuine choice about what to believe, and where evidence does not decide the matter, we are free to decide it however we want. Oour passional nature not only lawfully may, but must, decide an option between propositions, whenever it is a genuine option that cannot by its nature be decided on intellectual grounds. (127) In the relevant cases, we are not
