Substratum Definition & Meaning

This takes place mainly in
Metaphysics, Book Z. In the latter, the analysis of
substances in terms of form and matter is developed, whereas these
notions have no place in Categories. The distinction has led
some commentators to talk of Aristotle’s ‘two
systems’, containing two radically different conceptions of
substance (Graham 1987). In the earlier, Categories,
substances are simply individuals; in the later work they are
complexes of form and matter. Whether this represents a change of
view, or whether the purposes of the Categories simply did
not require reference to the metaphysical analysis of substance is a
moot point.

His theory is at least neutral on the question of whether there is a
closed system at the level of basic physics (Nussbaum 1978, 1984). Plato rejected these materialist attempts to explain everything on the
basis of that of which it was made. According to Plato, the governing
principles were the intelligible Forms, which material objects
attempted to copy. These Forms are not substances in the sense of
being either the stuff or the individuals or the kinds of individuals
out of which all else is constructed. Rather they are the driving
principles that give structure and purpose to everything else. The Forms
meet criterion (i)—ontological basicness—but in a slightly
eccentric way, because they do not, in a normal sense, constitute

In the absence of all three lines of evidence mentioned above, linguistic substrata may be difficult to detect. Substantial indirect evidence is needed to infer the former existence of a substrate. The nonexistence of a substrate is difficult to show,[11] and to avoid digressing into speculation, burden of proof must lie on the side of the scholar claiming the influence of a substrate. The principle of uniformitarianism[12] what is substratum and results from the study of human genetics suggest that many languages have formerly existed that have since then been replaced under expansive language families, such as Indo-European, Afro-Asiatic, Uralic or Bantu. However, it is not a given that such expansive languages would have acquired substratum influence from the languages they have replaced. In biochemistry, the substrate is a molecule upon which an enzyme acts.

  1. The enzymes are produced by the microbes to acquire nourishment and energy through the breakdown of very complex organic substrates.
  2. In chemistry, a substrate is typically thought of as a chemical material that can be acted upon by another material to induce a change.
  3. We shall
    consider various rationalist and empiricist treatments of the concept.
  4. Structure

    seen that the boundaries between these kinds are largely a matter of

Used by businesses, individuals, groups, or organizations that wish to host sites, databases, and applications on the network. These examples are programmatically compiled from various online sources to illustrate current usage of the word ‘substrate.’ Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors. The ontological status of complex bodies and ‘masses of
matter’ (in Locke’s phrase) is an issue very much under
dispute and we shall return to it below. How does Locke, then, rate against the six criteria for substancehood
that were set up in the introduction? Accepting, for these purposes,
that Locke believed in substratum, we can apply these tests both to
substratum, and to his ‘ideas of particular sorts of


Photosynthesis is the process that plants undertake to create organic materials from carbon dioxide and water, with the help of sunlight- all of which are investigated in this tutorial… Learn how the way genes control and determine every aspect of the body. The substrates may also be further differentiated from each other on the basis of the plants where they are meant to be applied. In particular, they are substrates for acidic plants, green plants, flowering plants, cacti, succulents, garden, orchids, carnivorous plants, rose bushes, and seed buds. They are commonly used in the mixture of peat, perlite, and organic fertilizers.

I say
‘implicit rationale’, because it seems no more natural to
speak of an object as being ‘wholly present at all temporal
points of its existence’ than it is to say that it has objects
as its temporal parts. Nevertheless, one does not think of a
long-lived object as consisting of a series of short-lived objects
stacked end to end, but one does think it natural to think of a
drawn-out event as consisting of a series of shorter events. If it is
not natural to think of objects as having objects as their temporal
parts, this seems to commit one to thinking of objects as wholly
present at all times of their existence, strange though this form of
expression may also be.

Because of his empiricism, he will not bring non-psychological
necessity into it. Nevertheless, there is the implication that making
these transitions is the only way in which one can understand
the world. Kant drops the empirical psychology and makes it a matter
of a priori psychology, that only by employing certain categories
could we have experience as of a physical world. It is only by
understanding the world as possessing enduring spatio-temporal
objects, which enter into causal relations with each other (that is,
it is only by applying the categories of substance and causation) that
we can have intelligible experience. Substances—that is, a
framework of stable, enduring objects—are essential, but the
source of this necessity lies not in how the world is in itself, but
in the framework that we are obliged to impose.

A phase sortal is one
that, by its meaning, denotes part of the life history of something,
which, as a whole, is denoted by another sortal. So child is
a phase sortal that applies to a phase of the things fully designated
by human being. It is a necessary condition for
F’s being an ultimate sortal that, whenever it applies
to something, it applies in a present-tensed manner to the thing
through the whole of its existence. F. Strawson (1959, 1966), this
framework of necessity is taken in a more common-sense and realist
spirit. The world must possess such enduring objects for it to be
intelligible for us—indeed, for us to be part of it, for we are
essentially stable bodies amongst other stable bodies.

Each of them
weighs, say, ten pounds, yet the total of their weight is only ten
pounds. It might seem natural to think—and it was formerly a
well established maxim—that there can be only one solid physical
thing at one place at a given time. Someone impressed by the idea that
two bodies cannot be in the same place at the same time might think it
more natural to say that there are two different ways of
conceptualising the material presence at that point, than that there
are two material things.

Any feature of it can, of course, be regarded as a
property, but that does not render an object nothing but a collection
of properties. There seems to be a clash of intuitions at this point
about what makes sense. An opponent of the deflationary view will say
that properties, however understood, must be components of objects,
conceptually or formally speaking.

They agree that, even if the world is
‘closed under physics’—every event has a complete
set of physical causes—the concepts of the other sciences are
irreducible and do autonomous explanatory jobs. Even if dogs are
wholly physical objects and even if all the atoms in dogs follow very
precise laws of physics, nevertheless when doing the biology of dogs
one will need concepts not to be found in a physics textbook. This is
not for mere shorthand convenience, but because of the kinds of things
in which, for example, the biologist or veterinary scientist is
interested. There are interpreters of Aristotle who think that this
kind of irreducibility is all that Aristotle means—or needs to
mean—by postulating an explanatory role for substantial form.

Similarly for properties or tropes, there can never be only one
because any one entails the existence of others, as, for example, the
existence of a red property (instance) entails the existence of (an
instance of) the property colour. By contrast, there could exist
through a period of time just one substance, provided that it was
atomic. This association of substance with kinds carries
over into a use of the term, which is perhaps more scientific,
especially chemical, than philosophical.

A superstrate may also represent an imposed linguistic element akin to what occurred with English and Norman after the Norman Conquest of 1066 when use of the English language carried low prestige. In the case of French, for example, Latin is the superstrate and Gaulish the substrate. As we saw above, for Wiggins the concept ‘body’ is always
generic, never sufficient in its own right to sustain identification,
needing to be filled out by appeal to a more determinate sortal, such
as ‘dog’ or ‘table’. Locke’s doctrine of sortals is in some respects realist and in
some conceptualist or conventionalist.
