As a question of science, the existence of the "vacuum" is doubtful. "It may be safely asserted that hitherto all attempts at producing a perfect vacuum have failed."--Grove, "Correlation of Physical Forces," p. 134. The general tendency of science is toward a denial of its existence (p. 137). As a question of metaphysics, the human reason can only find satisfaction in believing in a spiritual Being, a living Will which "inhabiteth eternity and immensity," and "filleth all in all" with living and life-giving fullness, so that "in Him we live and move and have being."--McCosh, "Intuitions of the Mind," p. 225.] [Footnote 75: "By empty space I mean _distance_, I mean _direction_: that steeple is a mile off, and not _here_ where I sit, and it lies southeast and not north."--Herschel, "Familiar Lectures on Scientific Subjects," p. 455.] [Footnote 76: Taylor, "Physical Theory of Another Life," p. 26.] [Footnote 77: "The idea of space--the idea of extension--is the logical condition of the admission of the idea of the body."--"History of Philosophy," vol. ii. p. 217.] [Footnote 78: "Extension is only another name for space."--"Lectures on Metaphysics," vol. ii. p. 113.] [Footnote 79: "Space and extension are convertible terms."--"First Principles," p. 48.] [Footnote 80: See "Intuitions," p. 223, where the terms are employed as synonymous.] [Footnote 81: "L'immensité ou l'unité de l'espace."--Cousin, "Histoire de la Philosophie du xviii^me Siècle," p. 121.
