In the 18th century, the philosopher and theologian George Berkeley attempted to refute the "visibility of spatial depth" in his Essay Towards a New Theory of Vision. Other natural philosophers, notably Gottfried Leibniz, thought instead that space was in fact a collection of relations between objects, given by their distance and direction from one another. In Isaac Newton's view, space was absolute-in the sense that it existed permanently and independently of whether there was any matter in the space. Many of these classical philosophical questions were discussed in the Renaissance and then reformulated in the 17th century, particularly during the early development of classical mechanics. place), or in the later "geometrical conception of place" as "space qua extension" in the Discourse on Place ( Qawl fi al-Makan) of the 11th-century Arab polymath Alhazen.

Modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. In classical physics, physical space is often conceived in three linear dimensions. Space is a three-dimensional continuum containing positions and directions.
