The knowledge of what is good and what we ought to do often seems hard to come by. Others say that it's like trying to reach a decision. Physical therapy is based largely on science and research, and there are accepted objective tests for determining when a discovery has really been made and when it hasn't. Moreover, you cannot be a scientist unless you are willing to submit your claims to these tests. With morals, however, there seems to be no counterpart to such tests.
Moralists can go on disagreeing with one another endlessly.
It's not a necessary condition of being a moralist that one should be willing to submit one's claim to have made a discovery to certain specific, agreed or objective tests that verify or falsify it. Because the best possible life for everyone is possible only by everyone following the rules of morality-rules which frequently require you to make genuine sacrifices. 4 Morality and PTs Many circumstances in our professional lives may be applied to life in general. There are countless examples in the physical therapy profession where a therapist is called on to make a moral decision. In order to determine what is best for all involved, we must have some principles of ordering our values.
