The two WOBs of sperm and egg bring them together. Both belong to processes that started in the past. Now they fuse, initiating a new process that emerges to become a human being. In order to control processes WOB requires information on their performance, or state. This information is called here instinct .
Processes interact and interleave.
Some are affected by the environment and induce WOB 's response. When it gets cold outside, performance of some process changes, and WOB may respond by shivering. Yet shivering can occur also due to internal causes, e.g. during fever. Generally, when an outside trigger induces a response it is regarded as instinctive reaction . Here we shall extend this definition to include inside triggers as well.
