Good Science is the pursuit of knowledge derived from questioning. It is the science that looks at a phenomenon and attempts to elucidate its workings through rational thought and empirical investigation. It strives to be as objective as possible in its process. Conclusions are eventually drawn following the thorough analysis of evidence, but the conclusions must not extend beyond the assumptions that so define the research.
There is no single definitive scientific method, but there are broad procedures that extend from the initial observation through hypothesis to the investigation, analysis, and subsequent conclusion(s) for any inquiry.
Scientists are not guardians of truth but agents of clarification that peel away the fog of noise in an attempt to model more accurately the workings of the world. They are, of course, free to philosophize and speculate about the significance of their findings (something I personally call the extended objective), but these speculations should not overwrite or even overextend the mandate of their original research.
The individual Scientist is bound to understand the limits of their findings which ultimately calls for an appreciation of the restrictions of their respective disciplines. Science is not a religion, nor should it be vaunted as one; however, it is the best tool that we humans have for understanding the material world. It is indeed very powerful, but it is ultimately confined to the milieu of matter/energy.
