This article argues that toleration understood as the principled restraint from the use of force is an instance of RG. Collingwood's 'ideal of civility' towards which liberalism as the process of civilisation aspires. In the first part of this article, Toleration as Civility, I draw on Collingwood's philosophy to provide an account of toleration as an instance of civility embodying self-respect, historical consciousness, and complete freedom of the will. Accordingly, the limits of toleration are conceived as necessarily informed by the (...) level of civilisation in society, and relativism in such limits in society is part of the dynamic of the process of civilisation towards a universal ideal, and not an end state in itself. In the second part, Toleration and 'Absolute Presuppositions', it will be shown that Collingwood's theory of atonement and his assertion of the Christian roots of liberalism supports a view of toleration as a moral 'attitude' which captures the elements of atonement (those being punishment, forgiveness, love and hope), and highlights the relevance of Collingwood's theory of 'absolute presuppositions' to contemporary issues in political philosophy.

This paper presents the nonlinear dynamic analysis of energy-based models arisen from the applied systems characterized by the energy transport in the presence of fractional order derivative and time delay. The studied model is the fractional version of Bianca-Ferrara-Dalgaard-Strulik model of economy which is viewed as a transport network for energy in which the law of motion of capital occurs. By considering the time delay as bifurcation parameter, a proof to investigate the existence of Hopf bifurcation and the phase lock (...) solutions using the Poincare-Linstedt and the harmonic balance methods is given. At definite values of time delay, period-doubling bifurcations followed up by the consequences of chaotic states are detected. Simulation results assure that the BFDS model can generate new chaotic attractors beyond half order derivatives through the effect of the time delay on that system. In accordance with the literatures related to the problem of chaos, the concluded results confirm the proposed theorem by El-Borhamy in which the time delay possesses the ability to change the dynamic state of nonlinear systems from regular to chaotic within the fractional order derivative domain.
