“As soon as questions of will or decision or reason or choice of action arise, human science is at a loss.”

Simplified Meaning:

When people make decisions or choose how to act, it's hard for science to explain why they do what they do. Science is great at explaining how our bodies work or how nature operates, but it struggles with the complexities of human thoughts and choices. For example, you might decide to spend time helping a friend instead of studying for an important test. While science can explain the stress and chemicals in your brain, it can't fully understand the personal reasons behind your choice. It’s challenging because everyone’s decisions are influenced by unique experiences, emotions, and values. To apply this idea, remember that human behavior often goes beyond simple, logical explanations; it’s important to consider the deeper personal reasons when trying to understand or predict someone's actions.
