Meaning of Substance

What is Substance:

It is known by the name of substance to all that matter whose properties and characteristics are stable and homogeneous. For example: “Water is a liquid substance.”

Substance is also called essence or the most important part of something. For example: “The substance of the speech was in the end.”

On the other hand, substance is also the set of characteristics of a thingwhich are stable and do not vary: “Today’s Catholic faith has lost its substance.”

Substance also refers to value, utility or significance of something: “Their contributions to public opinion are of little substance.”

Likewise, we call substance juice that they extract from fruits or food: “Get all the substance out of the lemon.”

In the same way, the substance is known as the nutritional quality of an edible: “The substance of the egg is in the yolk.”

The word substance is also used to refer to the level of judgment or good sense that a person shows: “Andrés seemed like a boy without substance, a bad match for his daughter.”

The word, as such, comes from the Latin substancewhich is formed from the prefix sub– meaning ‘under’ and the Latin verb stare, which means ‘to be’. In the countries of the Southern Cone it maintains a more conservative spelling with respect to its original etymology: substance.

substance in philosophy

In philosophy, substance is called foundation of reality. In fact, its very etymology suggests it: the word is formed from the prefix sub-which means ‘below’, and the Latin verb starewhich translates ‘to be’, in short: what is below, what underlies.

Aristotleon the Metaphysicswondered what the substance was, that is, the being in itself of thingsthat which “is” without the need for something else to be, as I would later say discards. And he considered that the opposite of the substance was the accident or the attribute. Thus, the substance is that which does not vary in being despite the modifications resulting from accidents. In this sense, the notion of substance is also associated with the philosophical concept of essence.

A substance is said to be pure when it cannot be broken down by physical means, although it can be broken down by chemical means. Pure substances, in turn, are subdivided into two types.

  • Simple pure substance: It cannot be decomposed, since it is made up of only one element. For example: oxygen.
  • Composite pure substance: It can be decomposed into more than one element. For example: water.
