Abstract Aristotle tells us that the Nicomachean Ethics is an “inquiry” and an “investigation” (methodos and zētēsis). This paper focuses on an under-appreciated way that the work is investigative: its employment of an exploratory investigative strategy—that is, its frequent positing of, and later revision or even rejection of, merely preliminary positions. Though this may seem like a small point, this aspect of the work’s methodology has important consequences for how we should read it—specifically, we should be open to the possibility that some contradictions in the text are the result of his employment of this investigative strategy. In the paper, I describe this investigative strategy, discuss what motivates Aristotle to employ it in the work, and go through three contradictions that are plausibly identified as examples of its use—specifically, his claims that courageous people do and do not fear death, that friendship is and is not mutually recognized goodwill, and that virtuous people do and do not choose noble actions for their own sake.

Area Efficient

In this paper, an area-efficient low power fast fourier transform (FFT) processor is proposed for multi input multi output-orthogonal frequency division multiplexing (MIMO-OFDM) in wireless communication system. It consists of a modified architecture of radix-2 algorithm which is described as modified radix-2 multipath delay commutation (MOD-R2MDC). The OFDM receiver with modified R2MDC (MOD-R2MDC) FFT was designed by Hardware Description Language (HDL) coding The Xilinx ISE Design Suite 10.1 is used as a synthesis tool for getting the power and area. The Model-Sim 6.3c is used for simulation. Also the existing OFDM system has been tested with these FFT algorithms and their performances were analyzed with respect to occupancy area in FPGA and power consumption. A low-power and area efficient architecture enables the real-time operations of MIMO OFDM system.

I am exhibiting a number of flakes and implements, which appear to be of Le Moustier date, from Acton on the Taplow Terrace, and West Drayton and Iver on the Boyn Hill Terrace.The Acton specimens are from the immediate vicinity of the working floor discovered by the late Mr. Allen Brown some forty years ago. During recent excavations in Creffield Road, I picked out of the brick-earth, thrown up from a depth of 4 to 6½ feet, seventy humanly struck flints. Forty-six are unpatinated, fresh-looking and unabraded, twenty have a bluey-white patination, amongst which are several with slightly dulled edges, and four are light-ochreous. The freshness of the cortex on several of the unpatinated flints suggests that some of the raw material was derived directly from the chalk. The majority are simple flakes and spalls. The remainder consists of eighteen small Levallois flakes, varying in size from 2 by 1½ to 3½ by 2¼ inches, one small tortoise core, a small flattish core with flaking on one face at right angles to that on the other, a flint pebble which has been used as a hammerstone, one small point and two exceptional pieces. One of these is a fairly typical graver (bee de flûte) with bluey-white patination (Fig. 1); the other may be described as a busked graver, it is made from a thickish external flake and is unpatinated (Fig. 2). A few of the flakes shew slight signs of use.
