Tradition as a Communication System. A Pragmatic Approach

A context of my paper is the debate on reason, tradition and traditional communities, in which this moral and epistemological issues were discussed as a part of general socio-philosophical theory of modernity. In particular I intend to locate my considerations in the context of formal-pragmatic theory of modern communicative rationality developed by Jürgen Habermas and Robert Brandom. I will provide a competitive model of the rationality of tradition by applying a conceptual toolkit of pragmatically oriented analysis to explain practices connected with vocabulary of tradition. I argue that tradition as a communication system has a fully rational structure. My main claim is that communicative structure of tradition has a rational structure of language game. This structure includes defined principles of communication for members of closed tradition-grounded community and rule of inclusion for potential new members. Firstly I consider closely internal principles of communication within the framework of tradition contrasting them shortly with normative-deontic rules of the postenlightenment idea of pragmatic communication discussed by Jürgen Habermas and Robert Brandom. After that I examine the rule of inclusion — the rule, which mediates between closed system of tradition-based community and his environment.Numer został przygotowany przy wsparciu Ministerstwa Nauki i Szkolnictwa Wyższego

Phonon-assisted decoherence and tunneling in quantum dot molecules

We study the influence of the phonon environment on the electron dynamics in a doped quantum dot molecule. A non-perturbative quantum kinetic theory based on correlation expansion is used in order to describe both diagonal and off-diagonal electron-phonon couplings representing real and virtual processes with relevant acoustic phonons. We show that the relaxation is dominated by phonon-assisted electron tunneling between constituent quantum dots and occurs on a picosecond time scale. The dependence of the time evolution of the quantum dot occupation probabilities on the energy mismatch between the quantum dots is studied in detail.Comment: 4 pages, 2 figures, conference proceeding NOEKS10, to be published in Phys.

Theory of phonon-mediated relaxation in doped quantum dot molecules

A quantum dot molecule doped with a single electron in the presence of diagonal and off-diagonal carrier-phonon couplings is studied by means of a non-perturbative quantum kinetic theory. The interaction with acoustic phonons by deformation potential and piezoelectric coupling is taken into account. We show that the phonon-mediated relaxation is fast on a picosecond timescale and is dominated by the usually neglected off-diagonal coupling to the lattice degrees of freedom leading to phonon-assisted electron tunneling. We show that in the parameter regime of current electrical and optical experiments, the microscopic non-Markovian theory has to be employed.Comment: Final extended version, 5 pages, 4 figure

Wokół świętości. Rozważania kulturoznawcze

The development of the concept of holiness is associated with the cultural process of separating the practical activity and the primary magical beliefs, termed by Max Weber's the ‘disenchantment of the world’. As a result, the sphere of human activity was divided into the sacred and the profane. Holiness was generally associated with the operation of variously recognised supernatural factors. In the Judeo-Christian tradition, it is an attribute of God's holiness. As a generalisation of all the virtues, it is endowed with the ethical dimension. The moral dimension of holiness and the specific rules of behaviour towards the sacred are reflected in everyday language,several sayings and proverbs
