In 1948 Hempel and Oppenheim proposed an explicatum for the concept of systematic power 1, pp. 164–167. Since that time some shortcomings have been found in this first attempt. It is the purpose of this paper to show that one can keep the basic approach of the ‘48 paper, and overcome the known disadvantages by means of changes in the details of the definition. In this improvement certain tools will be used that were not available in 1948.
In the main the contribution of Paul Oppenheim was limited to propounding some of the fundamental ideas. The authors wish to express their gratitude to C. G. Hempel for his constructive criticism.
