 Apart from this influence, and the continuing interest of his work as a theorist of religion, Feuerbach’s importance for the history of modern philosophy is also due to the fact that the publication of The Essence of Christianity in 1841 can be taken, as it was by Engels, to symbolically mark the end of the period of classical German philosophy that had begun sixty years earlier with the appearance of Kant’s Critique of Pure Reason—though some might want to question the assumption involved in this way of putting things that classical German philosophy culminated in the Hegelian system that Engels thought of Feuerbach as having overthrown. In any case, Feuerbach’s biography and the trajectory of his thinking are both closely intertwined with political and intellectual developments in the period referred to by historians as the Vormärz, which extends from  1830–1848.[1]  Although he remained unable to bring to fruition the “philosophy of the future”, the aphoristically formulated “principles” of which he attempted to set out in 1843, the emphases in his later essays on corporeality, the senses, finitude, inter-subjectivity, and drive psychology introduced into the history of modern thought themes developed further by Marx, Nietzsche, Freud, Martin Buber, Karl Löwith, Maurice Merleu-Ponty and Alfred Schmidt, among others.
