Substance (From Latin substantia for “substance, essence”, from substāns, substō for “exist" or literally, "stand under”) is a term indicating an essential quality of anything, especially the most vital aspects or portions. It also commonly refers to physical matter, or to anything with apparent substantiality, solidity, or firmness by various measures, including resources, property, or material possessions; in philosophy and theology it often refers to the hypostasis of reality, the cosmos, or God.
- Spinoza's use of the term finite tends to make space the only form of substance, and all existing things but affections of space, and this, I think, is really one of the ultimate foundations of his system.
- George Boole, in An Investigation of the Laws of Thought: On which are Founded the Mathematical Theories of Logic and Probabilities (1854), p. 215
- This Idea of Spinoza's we must allow to be in the main true and well-grounded; absolute substance is the truth, but it is not the whole truth; in order to be this, it must also be thought of as in itself active and living, and by that very means it must determine itself as mind. But substance with Spinoza is only the universal and consequently the abstract determination of mind ; it may undoubtedly be said that this thought is the foundation of all true views — not, however, as their absolutely fixed and permanent basis, but as the abstract unity which mind is in itself. It is therefore worthy of note that thought must begin by placing itself at the standpoint of Spinozism; to be a follower of Spinoza is the essential commencement of all Philosophy. For as we saw above … when man begins to philosophize, the soul must commence by bathing in this ether of the One Substance, in which all that man has held as true has disappeared ; this negation of all that is particular, to which every philosopher must have come, is the liberation of the mind and its absolute foundation.
- Our Substance is our Father, God Almighty, and our Substance is our Mother, God, All-wisdom; and our Substance is in our Lord the Holy Ghost, God All-goodness.
- Julian of Norwich, in Revelations of Divine Love (c.1393), Ch. 58
- We shall see when we come to Newton's laws of motion that in the words "so far as in it lies," properly understood, is to be found the true primary definition of matter, and the true measure of its quantity. Descartes, however, never attained to a full understanding of his own words (quantum in se est), and so fell back on his original confusion of matter with space — space being, according to him, the only form of substance, and all existing things but affections of space. This error runs through every part of Descartes' great work, and it forms one of the ultimate foundations of the system of Spinoza. I shall not attempt to trace it down to more modern times, but I would advise those who study any system of metaphysics to examine carefully that part of it which deals with physical ideas.
We shall find it more conducive to scientific progress to recognise, with Newton, the ideas of time and space as distinct, at least in thought, from that of the material system whose relations these ideas serve to co-ordinate.
- This identification of extension with substance runs through the whole of Descartes's works, and it forms one of the ultimate foundations of the system of Spinoza.

- Invention, it must be humbly admitted, does not consist in creating out of void, but out of chaos; the materials must, in the first place, be afforded: it can give form to dark, shapeless substances, but cannot bring into being the substance itself. In all matters of discovery and invention, even of those that appertain to the imagination, we are continually reminded of the story of Columbus and his egg. Invention consists in the capacity of seizing on the capabilities of a subject, and in the power of moulding and fashioning ideas suggested to it.
- By God, I mean a being absolutely infinite — that is, a substance consisting in infinite attributes, of which each expresses eternal and infinite essentiality.
Explanation — I say absolutely infinite, not infinite after its kind: for, of a thing infinite only after its kind, infinite attributes may be denied; but that which is absolutely infinite, contains in its essence whatever expresses reality, and involves no negation.
- Whatsoever can be perceived by the infinite intellect as constituting the essence of substance, belongs altogether only to one substance: consequently, substance thinking and substance extended are one and the same substance, comprehended now through one attribute, now through another. So, also, a mode of extension and the idea of that mode are one and the same thing, though expressed in two ways. This truth seems to have been dimly recognized by those Jews who maintained that God, God's intellect, and the things understood by God are identical. ...Thus, whether we conceive of nature under the attribute of thought, or under any other attribute, we shall find the same order, or one and the same chain of causes — that is, the same things follow in either case. ...Wherefore of things as they are of themselves, God is really the cause, inasmuch as he consists of infinite attributes.
- The being of substance does not appertain to the essence of man — in other words, substance does not constitute the actual being of man.
- Substance is in its nature infinite, immutable, indivisible...
- God, or substance, consisting of infinite attributes, of which each expresses eternal and infinite essentiality, necessarily exists.
- We are all made of the same stuff, remember, we of the Jungle, you of the City. The same substance composes us — the tree overhead, the stone beneath us, the bird, the beast, the star — we are all one, all moving to the same end. Remember that when you no longer remember me, my child.
- I have coined the phrase “Thinking is linking.” I thought of Kerenyi — “Mythology occupies a higher position in the bios, the Existence, of a people in which it is still alive than poetry, storytelling or any other art.” And of Malinowski — “Myth is not merely a story told, but a reality lived.” And, along with those, the word “Pollen,” the most pervasive substance in the world, kept knocking at my ear. Or rather, not knocking, but humming. What hums? What buzzes? What travels the world? Suddenly I found what I sought. “What the bee knows,” I told myself. “That is what I’m after.”
But even as I patted my back, I found myself cursing, and not for the first time, the artful trickiness of words, their capriciousness, their lack of conscience. Betray them and they will betray you. Be true to them and, without compunction, they will also betray you, foxily turning all the tables, thumbing syntactical noses. For — note bene! — if you speak or write about What The Bee Knows, what the listener, or the reader, will get — indeed, cannot help but get — is Myth, Symbol, and Tradition! You see the paradox? The words, by their very perfidy — which is also their honorable intention — have brought us to where we need to be. For, to stand in the presence of paradox, to be spiked on the horns of dilemma, between what is small and what is great, microcosm and macrocosm, or, if you like, the two ends of the stick, is the only posture we can assume in front of this ancient knowledge — one could even say everlasting knowledge.

- You do not chop off a section of your imaginative substance and make a book specifically for children, for — if you are honest — you have no idea where childhood ends and maturity begins. It is all endless and all one.
- P. L. Travers, as quoted in Sticks and Stones : The Troublesome Success of Children's Literature from Slovenly Peter to Harry Potter (2002) by Jack Zipes
