Which Dutch philosopher of Sephardi/Portuguese origin made a contribution in conatus?
Conatus In early philosophies of psychology and metaphysics, conatus ( ; Latin for "effort; endeavor; impulse, inclination, tendency; undertaking; striving") is an innate inclination of a thing to continue to exist and enhance itself. This "thing" may be mind, matter or a combination of both. Over the millennia, many different definitions and treatments have been formulated. Seventeenth-century philosophers René Descartes, Baruch Spinoza, Gottfried Leibniz, and Thomas Hobbes made important contributions. The "conatus" may refer to the instinctive "will to live" of living organisms or to various metaphysical theories of motion and inertia. Often the concept is associated with God's will in a pantheist view of Nature. The concept may be broken up into separate definitions for the mind and body and split when discussing centrifugal force and inertia.
Max Scheler Max Ferdinand Scheler (] ; 22 August 1874 – 19 May 1928) was a German philosopher known for his work in phenomenology, ethics, and philosophical anthropology. Scheler developed further the philosophical method of the founder of phenomenology, Edmund Husserl, and was called by José Ortega y Gasset "the first man of the philosophical paradise." After his death in 1928, Martin Heidegger affirmed, with Ortega y Gasset, that all philosophers of the century were indebted to Scheler and praised him as "the strongest philosophical force in modern Germany, nay, in contemporary Europe and in contemporary philosophy as such." In 1954, Karol Wojtyła, later Pope John Paul II, defended his doctoral thesis on "An Evaluation of the Possibility of Constructing a Christian Ethics on the Basis of the System of Max Scheler."
