*Division* and *Unity* are ubiquitious existential concepts. They are also closely related. In other words, *division* is derived from *wholeness* and *unity* is relevant within the context of *division*. *Division* and *unity* are implicit in the two most important existential operations of *addition* and *subtraction*. However, their existential importance requires their explicit treatment. The majority of *divisions* are positive. Negative *divisions* are very *loud* and potentially very harmful and so they are talked about more often. In fact, only one of the four classes of divisions I shall soon define, is constituted purely by negative divisions.

Let us use the mathematical definition of basic *division* to arrive at the definitions of our four classes of *divisions*. There are three components of basic mathematical division: the *dividend* (that which is to be divided); the *divisor* (that which is dividing the dividend); the *quotient* (the result of the division). We are particularly interested in the *polarities* (i.e. the *charges*, + or -) of the components. Let the space of interest be a multi-matter, multi-dynamic space (S_{7} in TECTechnics parlance) and let the *dividend* be the space of interest and the *quotient*, the space of interest after it has be acted upon by the *divisor*. The *divisor* may be contained within the space of interest or outside of it.

I make the following definitions:
*Positive dividend*: space is well (politically, economically, socially)
*Negative dividend*: space is unwell (politically, economically, socially)
*Positive divisor*: enhances the wellness of space.
*Negative divisor*: there are two types of *negative divisor*: one type disrupts and damages the wellness of space, the other type disrupts and damages the unwellness of space.
*Positive quotient*: wellness of space is enhanced or sustained after division. This is positive division.
*Negative quotient*: wellness of space is distrupted and damaged. Unwellness of space is established permanently or temporarily. This is negative division.

Now our four classes of divisions are as follows:
**(1)** *Positive quotient = positive dividend/positive divisor*.

This is in essence *unity*. *All* is well in the space and *all* is committed to enhancing the wellness of the space. For example, the partition of a space for more efficient administration; the genetic blueprint responsible for positive cellular division (e.g. somatic division). The question may arise as to why there are *divisors* if all is well with the space. The answer is that the *positive divisor* is a seeker of perfection which is an existential asymptote. Consequently, the *positive divisor* consistently seeks to enhance space as it tends towards perfection, making sure that *unity* is sustained.
**(2)** *Positive quotient = negative dividend/negative divisor *

This is a special case of division. It is usually the class of division with the most passion and also the class of division that has propelled human civilization. The space is unwell, the divisor is a disrupter and damager. Only in this case, the divisor is disrupting and damaging an unwell space. For example, a revolution that kicks out tyranny and then establishes a just governance; abolitionists that dethroned slavery and infact all bonafide freedom fighters are *negative divisiors* of *negative dividends*. The *negative dividend* does not have to be evil in character. For example, the space may be an inefficient space that *negative divisors* disrupt. This version of class two divisions is frequently encountered in the technological space.
**(3)** *Negative quotient = negative dividend/positive divisor *

This is the case of a noble *positive divisor* that is unable to realize its objective. It seeks to enhance space but it is over powered by the *negative dividend*. Consequently, its desire to obtain a *positve quotient* is unrealized. We see examples of this type of division when a group protests evil actions of their space. For examples, protesters who protest the unjust invasion of spaces. Their protest is overwhelmed by the power of the space.
**(4)** Negative quotient = postive dividend/negative divisor

This is the only *negative division*. The objective of the *negative divisor* is malicious from the onset and is often motivated by jealousy and resentment of success. The *dividend* is *positive* but the *negative divisor* resents the positivity. So it embarks on disrupting and damaging the space.The burning of *Black Wall Street* by racists groups is an example of this type of division.

Humans are basically animals dressed in fine clothings and possessors of distinguished intelligence. Many have used their intelligence and spirituality to refine their consciences. Many have not and will never. Consequently, there will always be humans who continue to prey on their fellow humans. Nonetheless, all is not lost, for we see in the classes of divisions that opportunities exist to change class (3) division into class (2) division and class (4) division into class (1) division. In other words, *negative divisors* of class (2) that can defeat the *negative dividends* of class (3) must come to augment the power of the noble *positive divisors* of class (3) and *positive divisors* of class (1) must come to kick out *negative divisors* of class (4). These senarios have occurred many times in human history.
