1El famoso método geométrico es una ardua formalización al servicio del rigor intelectual en la búsqueda de la verdad, cueste lo que cueste descubrir… - Benedictus de Spinoza

SOCIEDAD (civitas, respublica, multitudo) Surge de la composición — mediante pacto — de las potencias individuales, en aras de la común utilidad y del apetecido beneficio para todos (TP 2 y 3), y se generaliza como que nada hay más útil que el hombre para el hombre,

The philosophy of Descartes underwent a great variety of unspeculative developments, but in Benedict Spinoza a direct successor to this philosopher may be found, and one who carried on the Cartesian principle to its furthest logical conclusions. For him soul and body, thought and Being, cease to have separate independent existence. The dualism of the Cartesian system Spinoza, as a Jew, altogether set aside. For the profound unity of his philosophy as it found expression in Europe, his manifestation of Spirit as the identity of the finite and the infinite in God, instead of God's appearing related to these as a Third — all this is an echo from Eastern lands. The Oriental theory of absolute identity was brought by Spinoza much more directly into line, firstly with the current of European thought, and then with the European and Cartesian philosophy, in which it soon found a place.

...The doctrine of Spinoza was of great importance, if for nothing more than having brought about the first crisis in modern Philosophy.
