2. Scientists avoid using the terms “true” and “the truth” because they are too absolute. Science does not aim to give absolute knowledge. Instead, the scientific method relies on the senses and on experiments by creating hypotheses and testing them. Also, science is based on the five senses. The terms “true” and “truth” do not acknowledge the limitations of the five senses. Scientists understand that the body of knowledge created by science has changed over the years because of the development of better instruments to measure and gather data. The human senses might not change much, but the reliability of the senses change as instruments become more sophisticated.
Scientists are constantly striving to improve the reliability of their observations and so can never claim to know the “truth.” The five senses can point to what seems to be true, but scientists work with objectivity. Truth is a subjective issue, which is why religion and philosophy attempt to define truth.
