Space is a three-dimensional continuum containing positions and directions. In classical physics, physical space is often conceived in three linear dimensions. Modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework.
In the philosophy of space and time, eternalism is an approach to the ontological nature of time, which takes the view that all existence in time is equally real, as opposed to presentism or the growing block universe theory of time, in which at least the future is not the same as any other time. Some forms of eternalism give time a similar ontology to that of space, as a dimension, with different times being as real as different places, and future events are "already there" in the same sense other places are already there, and that there is no objective flow of time.
Mario Augusto Bunge was an Argentine-Canadian philosopher and physicist. His philosophical writings combined scientific realism, systemism, materialism, emergentism, and other principles.
In philosophy of science, confirmation holism, also called epistemological holism, is the view that no individual statement can be confirmed or disconfirmed by an empirical test, but rather that only a set of statements can be so. It is attributed to Willard Van Orman Quine who motivated his holism through extending Pierre Duhem's problem of underdetermination in physical theory to all knowledge claims.
Background independence is a condition in theoretical physics that requires the defining equations of a theory to be independent of the actual shape of the spacetime and the value of various fields within the spacetime. In particular this means that it must be possible not to refer to a specific coordinate system—the theory must be coordinate-free. In addition, the different spacetime configurations should be obtained as different solutions of the underlying equations.
Philosophy of space and time is the branch of philosophy concerned with the issues surrounding the ontology and epistemology of space and time. While such ideas have been central to philosophy from its inception, the philosophy of space and time was both an inspiration for and a central aspect of early analytic philosophy. The subject focuses on a number of basic issues, including whether time and space exist independently of the mind, whether they exist independently of one another, what accounts for time's apparently unidirectional flow, whether times other than the present moment exist, and questions about the nature of identity.
In theoretical physics, geometrodynamics is an attempt to describe spacetime and associated phenomena completely in terms of geometry. Technically, its goal is to unify the fundamental forces and reformulate general relativity as a configuration space of three-metrics, modulo three-dimensional diffeomorphisms. The origin of this idea can be found in an English mathematician William Kingdon Clifford's works. This theory was enthusiastically promoted by John Wheeler in the 1960s, and work on it continues in the 21st century.
"Is Logic Empirical?" is the title of two articles that discuss the idea that the algebraic properties of logic may, or should, be empirically determined; in particular, they deal with the question of whether empirical facts about quantum phenomena may provide grounds for revising classical logic as a consistent logical rendering of reality. The replacement derives from the work of Garrett Birkhoff and John von Neumann on quantum logic. In their work, they showed that the outcomes of quantum measurements can be represented as binary propositions and that these quantum mechanical propositions can be combined in a similar way as propositions in classical logic. However, the algebraic properties of this structure are somewhat different from those of classical propositional logic in that the principle of distributivity fails.
Hans Reichenbach was a leading philosopher of science, educator, and proponent of logical empiricism. He was influential in the areas of science, education, and of logical empiricism. He founded the Gesellschaft für empirische Philosophie in Berlin in 1928, also known as the "Berlin Circle". Carl Gustav Hempel, Richard von Mises, David Hilbert and Kurt Grelling all became members of the Berlin Circle.
Adolf Grünbaum was a German-American philosopher of science and a critic of psychoanalysis, as well as Karl Popper's philosophy of science. He was the first Andrew Mellon Professor of Philosophy at the University of Pittsburgh from 1960 until his death, and also served as co-chairman of its Center for Philosophy of Science, research professor of psychiatry, and primary research professor in the department of history and philosophy of science. His works include Philosophical Problems of Space and Time (1963), The Foundations of Psychoanalysis (1984), and Validation in the Clinical Theory of Psychoanalysis (1993).
Larry Laudan was an American philosopher of science and epistemologist. He strongly criticized the traditions of positivism, realism, and relativism, and he defended a view of science as a privileged and progressive institution against popular challenges. Laudan's philosophical view of "research traditions" is seen as an important alternative to Imre Lakatos's "research programs".
Jerzy Giedymin was a philosopher and historian of mathematics and science.

Milič Čapek, was a Czech–American philosopher. Čapek was strongly influenced by the process philosophy of Henri Bergson and to a lesser degree by Alfred North Whitehead. Much of his work was devoted to the relation of philosophy and modern physics, especially the philosophy of space and time and metaphysics.
The Foundations of Psychoanalysis: A Philosophical Critique is a 1984 book by the philosopher Adolf Grünbaum, in which the author offers a philosophical critique of the work of Sigmund Freud, the founder of psychoanalysis. The book was first published in the United States by the University of California Press. Grünbaum evaluates the status of psychoanalysis as a natural science, criticizes the method of free association and Freud's theory of dreams, and discusses the psychoanalytic theory of paranoia. He argues that Freud, in his efforts to defend psychoanalysis as a method of clinical investigation, employed an argument that Grünbaum refers to as the "Tally Argument"; according to Grünbaum, it rests on the premises that only psychoanalysis can provide patients with correct insight into the unconscious pathogens of their psychoneuroses and that such insight is necessary for successful treatment of neurotic patients. Grünbaum argues that the argument suffers from major problems. Grünbaum also criticizes the views of psychoanalysis put forward by other philosophers, including the hermeneutic interpretations propounded by Jürgen Habermas and Paul Ricœur, as well as Karl Popper's position that psychoanalytic propositions cannot be disconfirmed and that psychoanalysis is therefore a pseudoscience.
The Structure of Science: Problems in the Logic of Scientific Explanation is a 1961 book about the philosophy of science by the philosopher Ernest Nagel, in which the author discusses the nature of scientific inquiry with reference to both natural science and social science. Nagel explores the role of reduction in scientific theories and the relationship of wholes to their parts, and also evaluates the views of philosophers such as Isaiah Berlin.
The Degrees of Knowledge is a 1932 book by the French philosopher Jacques Maritain, in which the author adopts St. Thomas Aquinas’s view called critical realism and applies it to his own epistemological positions.According to critical realism, what we know is identical with what exists, and to know a thing is for its ‘essence’ to exist immaterially in the mind. In The Degrees of Knowledge, Maritain applies this view as he seeks to explain the nature of knowledge, not only in science and philosophy, but also in religious faith and mysticism. Maritain argues that there are different ‘kinds’ and ‘orders’ of knowledge and, within them, different ‘degrees’ determined by the nature of the thing to be known and the ‘degree of abstraction’ involved. The book is divided into two parts: Part one discusses the degrees of knowledge for science and philosophy – or ‘rational knowledge,’ and part two discusses the degrees of knowledge for religious faith and mysticism – or ‘super-rational knowledge.’
