Definition
Assume that the experiment is important, but one which we never consider conducting on a human being.
Either the thing which we are considering using as a surrogate (model of human physiology) is not like us, or it is like us.
If the thing is not like us, then there is no benefit that we will get from the experiment, and we ought not perform the experiment (e.g., oysters and trees).
If the thing is like us, then due to the principle of equality, we ought not perform the experiment (e.g., squirrels and orphans).
Therefore, we ought not perform the experiment. |
