The Law of Contact or Contagion, the second sublaw of the Law of Association, follows from the Law of Similarity. This law states that things which have once been in contact with each other continue to act on each other at a distance even after physical contact has been severed.
This can be shown by the following example: the something or commodity «C» which is similar to and was shared by thing «A» and thing «B» can after its detachment from «A» and «B» affect or control either or both. The mutual, influencing effect or control these things exert upon each other is dependent upon the greatness with which «C» was shared.
