The four basic qualities also referred to as the sensible qualities, and the elemental qualities are the four properties of hot, dry, cold, and wet. These understandings were used in humorism, and greek philosophy, and were also brought into occult philosophy, along with the classical four elements. Each one of these qualities has its own correspondences, that are unique to them, and work in accordance with the other three qualities in order to facilitate dynamic harmony within the paradigm. Hot, and cold are the primary qualities, or active qualities, and Dry and Wet are the secondary qualities, or passive qualities. Hot, and cold are the primaries, because they have the ability to go through the process of creating dryness, and wetness from their existence, or action. Hot, and cold are also sometimes referred to as first qualities, and dry, and wet are sometimes referred to as second qualities. Hot, and dry is connected to masculine energy, and yang energy. Cold, and wet is connected to feminine energy, and yin energy. Hot, and cold are on a polarity spectrum, and dry, and wet are also on a polarity spectrum. These two polarities spectrums intersect like a cross influencing each other with their actions, and their existence in different constructs, and environments. Aristotle was the person who associated these qualities to the elements. He understood that the element of fire was hot, and dry, the element of air was hot, and wet, the element of Earth was cold, and dry, and the element of water was cold, and wet. Through this understanding we could understand more about the metaphysical properties of each element, and how they relate to each other. By understanding these four qualities you will be able to understand the different interactions between constructs, and how you will be able to use one of these qualities to affect another one.
Hot is also sometimes referred to as warm. The things that fall into the quality of hot have high energy and high activity in their being. hot is warm, bright, and dynamic. Hot is very active, moves freely, and expands. When hot is active it can go through the process of creating the quality of dry. hot is primary, active, masculine, and it is connected to yang. It is also connected to the elements of fire, and air. hot is also connected to high places, or the above
The things that fall into the quality of cold have low energy, and low activity in their being. Cold is very slow, constricted, and condense. Cold is cool, dark and stagnant. Cold can go through the process of creating wet through its activity. Cold is primary, passive, feminine, and it is connected to yin. It is also connected to the elements of earth, and water. cold is also connected to low places or the below.
Dry can created from the activity of the quality of hot. Dry is hard, brittle, parched, or solid. Dry has the properties of Separation, objectivity, and discreteness. Dry is secondary, active, masculine, and it is connected to yang. It is also connected to the elements of fire, and earth.
