"Action seems to follow feeling, but really action and feeling go together; and by regulating the action, which is under the more direct control of the will, we can indirectly regulate the feeling, which is not"

In the quote by William James, a prominent philosopher and psychologist, an extensive insight into the interaction in between actions and sensations exists. James suggests that while it might appear that sensations naturally result in actions, the relationship is more reciprocal and interconnected. The essence of this quote is the notion that actions and feelings are not in a direct cause-and-effect relationship but rather exist in a vibrant, synergistic loop.

First of all, James highlights the common misconception that sensations constantly precede and determine our actions. While it often appears that we act based upon how we feel, he proposes that our actions can substantially affect our feelings. This challenges the traditional view by recommending that sensations can likewise be formed and customized by our actions.

The crucial point of James's argument lies in the role of the will. He presumes that while we might not have direct control over our sensations at any given moment, we do have more direct control over our actions. By consciously picking to regulate our actions, we can indirectly influence and shape our emotion. For example, selecting to engage in favorable behaviors, such as assisting others or practicing thankfulness, can foster favorable feelings like happiness and satisfaction.

James's insight is foundational for certain healing practices, such as cognitive-behavioral treatment, which emphasizes altering thought patterns and habits to affect emotions. It empowers people to recognize their agency in shaping their emotional experiences, recommending that proactive behavioral changes can cause a change in sensations gradually.

In summary, William James's quote encapsulates an empowering concept of psychological policy: by taking intentional control of our actions, we can indirectly manage and alter our emotions, hence developing a harmonious balance between how we act and how we feel. It encourages a proactive technique to individual growth, highlighting the power of willful action in shaping our psychological landscapes.
