Pharmacology gives us insight into the way organic processes change when foreign compounds are introduced into the organism.
Pharmacology is a changeable subject, contingent on the needs and knowledge of the time. Can we find an inner coherence in the manifold ways compounds influence organisms? What should such a framework be based on? How can we understand the effect on human consciousness that most compounds have?
We can enhance the scope of the answers to these questions by using a combination of the current scientific method and the 4-step approach. This illumes the well-known facts about the activity of compounds in organisms, and provides the means to find their significance.
