Toland et Leibniz : l'invention du néo-spinozisme
No full text"Cette étude prend pour point de départ l'échange entre Leibniz et Toland (1701-1702) sur la religion naturelle, la réflexion, l'immortalité de l'âme et la nature de la substance. Ce débat est à l'origine des célèbres "Lettres à Serena" (1704). Dans sa confrontation avec Toland, qui constitue un moment charnière de la genèse des "Nouveaux essais" , Leibniz discute les thèses de Locke sur la réflexion et rédige pour l'occasion sa "Lettre sur ce qui passe les sens et la matière" , où il entreprend d'inscrire la topique des connaissances, exposée dans ses "Méditations" de 1684, dans l'architectonique du "Système nouveau" . John Toland est connu pour avoir soutenu, dans ses "Lettres" , que « la matière est aussi essentiellement active qu'elle est étendue », de même que pour son projet d'une philosophie « panthéiste ». Souvent interprété comme un simple gauchissement matérialiste de la pensée de Spinoza, ce panthéisme trouve au contraire son origine dans une critique de la doctrine spinoziste et cartésienne de l'attribut. Tirant la leçon de la réforme leibnizienne de la notion de substance, mais aussi des controverses contemporaines sur le dynamisme newtonien et la métaphysique de la participation (Henry More, Anne Conway et Georg Wachter), Toland livre une série d'arguments et de thèses originales, qui marqueront de manière décisive la pensée des Lumières.

Consecuencias políticas del movimiento: John Toland ante Spinoza y Newton
No full textIn the last two Letters to Serena (1704), John Toland studies the conceptions of motion present in Baruch Spinoza and Isaac Newton. Before the first, Toland notes that he did not take a step that his system required of him, namely, to declare motion essential to matter. In the second case, his warning is different: Newton would have taken that step, although he would not have publicly exposed all the consequences that derive from it. In both cases, what interests us is the relationship between natural philosophy and political philosophy that Toland detects and that has not always been analyzed.En las dos últimas Cartas a Serena (1704), John Toland estudia las concepciones del movimiento presentes en Baruch Spinoza e Isaac Newton. Frente al primero, Toland advierte que no dio un paso que su sistema le exigía, a saber, declarar el movimiento esencial a la materia. Frente al segundo, su advertencia es diferente: Newton sí habría dado ese paso, aunque no habría expuesto públicamente todas las consecuencias que se derivan de este. En ambos casos, lo que nos interesa es la relación entre filosofía natural y filosofía política que Toland detecta y que no siempre ha sido analizada
Bifurcation and secondary bifurcation of heavy periodic hydroelastic travelling waves
No full textThe existence question for two-dimensional symmetric steady waves travelling on the surface of a deep ocean beneath a heavy elastic membrane is analyzed as a problem in bifurcation theory. The behaviour of the two-dimensional cross-section of the membrane is modelled as a thin (unshearable), heavy, hyperelastic extensible rod, and the fluid beneath is supposed to be in steady two-dimensional irrotational motion under gravity. When the wavelength has been normalized to be 2π, and when gravity and the density of the undeformed membrane are prescribed, there are two free parameters in the problem: the speed of the wave and the drift velocity of the membrane. It is observed that the problem, when linearized about uniform horizontal flow, has at most two independent solutions for any values of the parameters. When the linearized problem has only one normalized solution, it is shown that the full nonlinear problem has a sheet of solutions consisting of a family of curves bifurcating from simple eigenvalues. Here one of the problem's parameters is used to index a family of bifurcation problems in which the other is the bifurcation parameter. When the linearized problem has two solutions, with wave numbers k and l such that max{k,l}/min{k,l} ∉ Z it is shown that there are three two-dimensional sheets of bifurcating solutions. One consists of "special" solutions with minimal period 2π/k; another consists of "special" solutions with minimal period 2π/l; and the third, apart from those on the curves where it intersects the "special" sheets, consists of "general" solutions with minimal period 2π. The two sheets of "special" solutions are rather similar to those that occur when the linearized problem has only one solution. However, points where the first sheet or the second sheet intersects the third sheet are period-multiplying (or symmetry-breaking) secondary bifurcation points on primary branches of "special" solutions. This phenomenon is analogous to that of Wilton ripples, which arises in the classical water-wave problem when the surface tension has special values. In the case of Wilton ripples, the coefficient of surface tension and the wave speed are the problem's two parameters. In the present context, there are two speed parameters, meaning that the membrane elasticity does not need to be highly specified for this symmetry-breaking phenomenon to occur

Steady periodic water waves under nonlinear elastic membranes
No full textThis is a study of two-dimensional steady periodic travelling waves on the surface of an infinitely deep irrotational ocean, when the top streamline is in contact with a membrane which has a nonlinear response to stretching and bending, and the pressure in the air above is constant. It is not supposed that the waves have small amplitude. The problem of existence of such waves is addressed using methods from the calculus of variations. The analysis involves the Hilbert transform and a Riemann-Hilbert formulation
