The real question is whether we will use, more judiciously, the examples of the past to improve the lives of all in the future. If history is our guide, the answer is, “Yes, we can but, no, we won’t.” However, there is hope. After all, we are human beings. Closer to our professional home, what is the role of science in addressing racism, sexism, and religious intolerance? Do we consider who is the author of data or just the validity of the data? Do we weigh the quality of the data without considering its source? Do we, as scientists, bring total objectivity to our profession? Recent examples in the literature indicate that, no matter how much we profess otherwise, scientists are just another slice of humanity, in which (hopefully no more than) a small fraction operates on their prejudices under the false guise of objective, scientific judgments. However, there is hope. After all, scientists are human beings too. Richard G.
