Im often asked how the two work togather. To begin with one should look to history as an witness. Throughout history virtually all cultures had slavery. A very obvious domination/submission dynamic. There has also always been a flurishing sex trade (i.e.Legalised Prostitution) In Celtic culture such positins were viewed as wholely appropriate and even nesecary. Amongst the Druii who were amongst the most progressive to serve would have been and still is viewed as an honerable way to life.
Within the Kink Dynamic the Dom derives his/her status directly from the sub. Very like the Celtic concept of the king and the land. As the sub is lead to growth through the tutalidge of the dom. and thereby flowers into its full capacity. The relationship is benificial to both. In the relationship of the king in celtic thinking, the king or dom is only successful when the land/people flourish. He can only remain king as long as he serves the land, if he fails, he is deposed. In this example the sub is the land.
In this same vain the relationship of the merchant lords of japan held the same relationship. (see james clavels Noble House) The Tai Pans where the virtual total law and total power, yet thier very eistence depended on not only the understanding of merchandising, but upon the subissive ownership of and obedience of the servants, often whole famillies, who saw to every need of the Tai Pan.
Within each of these systems the submissive position was vital. One can very easilly see that a Dom without the power exchange ofered by those who submit is nothing. It should be noted that a subissive in these relationships hold a serious amount of power which he/she offers up to the Dom.
