Besides the theories, facts, and logical/strong evidences, there are numerous concepts of the philosophy of science in neurosurgery that are difficult to understand in practice. For example, do ?numbness,? ?pain,? and ?visual analog score? mean the same to the patient and the doctor? Can mechanical low back pain and instability be a real subject of the philosophy of science in the same phenomenon; how can a concept of movement-?instability? explain the cause of a concept of sensation-?pain?? Can concepts from entirely different categories like ?dynamic stabilization? occur in the same scientific explanation?

There are also some problematic terms that remain unsolved such as ?observable? and ?unobservable,? which gradually increase with technological advances in neuroscience.

In conclusion, these types of subjects not only affect the basis of our ?scientific knowledge? but also the relationships with our patients and colleagues; it is essential to ?understand? and be ?understandable.? We should bring ?scientific perspectives? to these issues by using critical, analytical, and integrative features of philosophy.
