Being and Time is the 1927 magnum opus of German philosopher Martin Heidegger and a key document of existentialism.

Concluding Unscientific Postscript to the Philosophical Fragments is a major work by Søren Kierkegaard. The work is a poignant attack against Hegelianism, the philosophy of Hegel, especially Hegel's Science of Logic. The work is also famous for its dictum, Subjectivity is Truth. It was an attack on what Kierkegaard saw as Hegel's deterministic philosophy. Against Hegel's system, Kierkegaard is often interpreted as taking the side of metaphysical libertarianism or freewill, though it has been argued that an incompatibilist conception of free will is not essential to Kierkegaard's formulation of existentialism.

In the preface to the first edition, Kant explains that by a "critique of pure reason" he means a critique "of the faculty of reason in general, in respect of all knowledge after which it may strive independently of all experience" and that he aims to reach a decision about "the possibility or impossibility of metaphysics."

Parts of the book were published in the Independent Magazine in July and August 1908.

Its main intellectual influences are Darwinism and certain German thinkers Wells had read, such as August Weismann. The pragmatism of William James, who had become a friend of Wells, was also an influence.
