The
following diagram and inference analysis are complete in coverage of the topics
of diagram construction and single inference analysis only. Premise
problems are not considered here, nor is a final analysis required or
provided.
Argument
Civil rights groups have
argued that using criminals as research subjects constitutes a violation of
their civil rights. They argue that the inmates are sometimes not
anesthetized when experiments are conducted, that they are subjected to
experimental drugs whose side effects are unknown until experimentation is complete,
and that there is a possibility that many of them will suffer death due to this
research. In addition, they argue that state governments should not
permit the inmates to volunteer for any such research since in doing so, they
are to be held just as accountable for any harm that comes to those who volunteer
as subjects as the labs themselves.
Diagram
With
Numbered Propositions
1. Using
criminals as research subjects is a violation of their civil rights.
2. They
(the inmates) are sometimes not anesthetized during the experimentation.
3. The
inmates are subjected to drugs whose side effects are unknown.
4. There
is a possibility of death resulting from the research.
5. State
governments should not permit inmates to volunteer as research subjects.
6. State
governments are to be held accountable for harm that comes to the volunteers.
(The
following explanation of the diagram is simply an informative device for the
benefit of the reader. When anyone diagrams and analyzes an argument, it
is not necessary to explain why the diagram was done in the way in which
it is presented. The analysis that will accompany the argument diagram
will explain, in itself, why one constructed the diagram as presented.)
After reading through the argument,
one may believe that the civil rights group mentioned appears to be arguing for
one point only, but in fact, it is entirely possible that they are not arguing
primarily that the rights of the inmates are being violated, but that someone
must be held accountable for any harm that comes to them as a result of these
alleged violations. If this is the case (other viewpoints could be argued
on the basis of the proper diagram) then the diagram presented provides three
equally important reasons why (2) is an intermediate conclusion. First,
however, one must take into account that by "rights", the civil
rights groups are referring to the right to life and the preservation of
health, not to other rights that might be covered under the general heading of
"civil rights." If this is true, then one may infer that the
rights of the inmates are being violated because their lives and health are in
jeopardy. And if this is true, then since state governments control the
lives of the prisoners in state facilities, they have the power to enforce the
prohibition on the inmates subjecting themselves to the research.
Furthermore, if one assumes that to have control over someone's activity, and
permitting someone under one's control intentionally or unintentionally to
subject themselves to harm or death, implies accountability for the actions of
those people, then proposition (6) is the main conclusion of the argument.
If one has followed closely the
explanation above, then it is clear that there are also implicit assumptions
involved in the argument. Those implicit assumptions include the
contentions that (1) state governments control the lives of the inmates in
state facilities, (2) state governments have the power to prohibit volunteering
for research, and (3) one who has control over another person's actions is
responsible for the results of those actions. Thus, either the diagram
must be altered to accommodate those assumptions, or when providing an
analysis, those assumptions should be discussed in order to argue for your
decision indicating the strength or weakness of the argument. If one
decides to add the implicit assumptions in the diagram, the analysis will bear
these points out. The principle of charity may require the addition of an
implicit conclusion. Fortunately, it is never necessary to add any
implicit statement to a diagram unless it is a conclusion.

Analysis
Inference
One, 2 + 3 + 4
---> 5. The inference from the three given basic premises, i.e., from
the statements that no anesthesia is given, death may result, and the side
effects may be undesirable, to the intermediate conclusion that state
governments should not permit inmates to volunteer as research subjects, is
subject to interpretation. (It will be the case that when one is
providing a diagram and analysis for an argument, it will be necessary to
provide only one point of view.) If one believes that a prison inmate is
little more than a child who cannot make his own decisions, then one also
believes that someone else is responsible for the decisions of that
person. If this is the case, then there is a good possibility that the
inmates should not be permitted to volunteer themselves for research. But
there apears to be something missing. "For what reason should they
not be permitted to volunteer?" The argument leaves the answer to
this question to the reader. To provide strength to the argument (as
required by the principle of charity), one could make the statement that
"anyone who is not considered responsible enough to behave in such a way
to keep himself out of jail should not be permitted to subject himself to the
possibility of life and health threatening research." This statement
provides the reason that the inmates should not be permitted to volunteer, and
may make the argument stronger than it would have been otherwise.
Inference
Two, 5 --->
1. If we accept that a person's rights are violated when some action or
affliction is imposed upon him either against his will or when he is incapable
of making his own decision either through his circumstances or his own choice,
then it may be the case that an inmate subjecting himself to such treatment
constitutes a violation of his rights. One could claim that this is
roughly analogous to permitting a child to experiment with a dangerous drug
(with parental knowledge) on the basis of the child's own decision. It
would be generally accepted that a child is incapable of making a rational
choice in such matters, and that to permit the child to subject himself to such
a substance is wrong on the part of the parent. And if a state
correctional facility has a role roughly analogous to the role of a parent to a
child, then the state is violating the rights of the criminals.
Inference
Three, 1
---> 6. The third and final inference of the argument may be strong
since a person or group responsible for the well-being of others can be held
accountable for harm that comes to those under their control. Again, if
we use the analogy that inmates are little more than children who are incapable
of making their own decisions, and if parents are responsible for any harm that
comes to children from activities in which they were permitted to engage, then
state governments are to be held accountable for harm to the volunteers.
