An atom or radical whose valence is one, or which can combine with, be replaced by, or exchanged for, one atom of hydrogen.
From the Greek word meaning "unit." Pythagoras used the word to denote the first number of a series, and Gottfried Wilhelm von Leibniz used the word to denote the unextended, simple, soullike basic elements of the universe.
means unity or unit, and Leibniz argued in Monadology that only units can be substances.
(1) Among the Pythagoreans (followers of Pythagoras) the monad was the first thing that came into existence. The monad begot the dyad, which begot the numbers, the numbers begat points, which begot lines, which begat two-dimensional entities, which begat three-dimensional entities, which begat bodies, which begot the four elements earth, water, fire and air, from which the rest of our world is built up. The monad was thus a central concept in the cosmology of the Pythagoreans, who held the belief that the world was - literally - built up by numbers. (2) Within certain variations of Gnosticism, especially those inspired by Monoimus, the Monad was the higher being which created lesser gods, or elements (similar to aeons). This view was according to Hippolytus inspired by the Pythagoreans.
an atom having a valence of one
an absolutely closed windowless cell
The One, The Absolute, unity undifferentiated and formless.
The Father-God of man. A star-ray of the Absolute. Our Father in Heaven. Source of the Higher and Lower Selves.
A primary organic unit. A chemical element having a valency of one. The monad played a central role in the idealist philosophy of Leibniz.
In many Gnostic systems (and heresiologies), God is known as the Monad, the One, The Absolute Aion teleos (The Perfect Æon), Bythos (Depth or Profundity, Βυθος), Proarkhe (Before the Beginning, Ï€ÏοαÏχη), and E Arkhe (The Beginning, η αÏχη) and The ineffable parent. God is the high source of the pleroma, the region of light. The various emanations of God are called æons.
