There are plenty of people and established organizations, experts, and scientists that will assert, with full confidence, a "complete" explanation for something in nature and decry further examination. This is part of the arrogance of the academic class that assumes they know everything there is to know about something. I categorically disagree that you do not need to have both some humility in your own understanding and some rejection of the status quo of current understanding (the word dissident was used here, I feel this captures the idea) to have the curiosity to pursue study that others reject. Pure science exploration is continuously challenged by experts and administrators holding the purse strings in the pursuit of something more marketable, profitable, or easily reproducible (think something like iterative changes to drugs to be different enough to patent but similar enough to have the same effects and use the same processes of manufacture).
