Properties of the number 2

Symbolism

Number of the God-Son (the Verb) within Trinity, in the Christian symbolic.
If 1 is the essence, 2 is the existence.
Symbol of the duality, the opposition, the separation, the antagonism.
The 2 is the first number to be deviated from the unit, said Hugues of Saint Victor, and because of that it symbolizes the sin. It is also the first number which admits the division, symbolizing the corruptible things.
Symbolize the love, the charity, since there is necessarily duality between which gives and which receives.
Symbol of sexuality since 2 represents also the division of the unit in male and female.
The principle of the duality can be represented in the form of couple or pair, and would imply the idea of direct and reciprocal reports of simple complementary relations. According to Eckarthausen, "2 is the Number by which one is united to the other and by what only all parts of the world make one."
The second term of a duality is often considered as a negation or a limitation of the first: the Devil, "telling always no", and the Evil which it personifies, have the number 2 for symbol. According to Claude of saint Martin, "2 is the opposition to the Unit, of its production; 2 comes out of 1 only by violence, because nothing from 1 is removed; it is to make pass the entire to the quality of half; it is the origin of the Evil". Madrolle tells that 2 is a false number, ugly, weak, sterile and unhappy. The original sin has consisted to steal to the tree of the garden of Eden (symbol of the unit) the fruit of the knowledge of the good and the evil (symbol of the dualism).
A favorable number as a symbol of the facility.
The 2, which defines the line after the point, represents the entry in the time after the indivisible and incorruptible unit.

In the man, the mechanism of the thought operates by dichotomy. The man cannot get any idea in himself of an absolute manner, but he recognizes the relationship between two ideas.

All idea has its negation by which it is clear and distinct".
