The more members of a social circle a civilisation element reaches, the more likely it is to spread further within that circle.
- Explanation. Reach means the number or proportion of members of a social circle who encounter a civilisation element. As a civilisation element reaches a larger part of the circle, it becomes more likely to spread further within that circle into the personal civilisations of its members. There is therefore a critical value for the further dissemination of civilisation elements.
