Rehabilitating Johann Adam Möhler's Sacramental Insights

The sacramental and liturgical propositions of the German theologian Johann Adam Möhler (1796–1838) have been neglected in theological inquiries thus far. This article attempts to rehabilitate them. Having established a particular perspective on the reading of Möhler's liturgical and sacramental insights, we present each dimension of them separately in order to arrive at a ‘dialectical’ sacramental model. This rereading is an intrinsic possibility stemming from Möhler's theological works themselves. In addition, it is also possible to rehabilitate these insights in interplay with some contemporary developments in liturgical and sacramental theology. In his symbolical understanding, Möhler anticipates the Realsymbol of Karl Rahner, and his understanding of the actual presence of the person and sacrifice of Christ in the Eucharist anticipates Odo Casel's Kultmysterium. Therefore, the rehabilitation of Möhler's sacramental insights exhibits its full meaning as the anticipation of a more accurate notion of Symbol.     

Köhler rediscovered: The anti-ringelmann effect

A current focus of research on individual versus group performance is social loafing, the decrease in individual effort that occurs when the individual works within a cooperative group rather than alone. This result is also referred to as the ‘Ringelmann effect’. But what has been ignored until now is the increment in group performance through systematic variation of individual performance rates within the group, although this effect was reported by Moede (1927) in the same article which influenced research on the Ringlemann effect. Within a narrow range of performance rates from 4.5 to 3.5 in dyads Kohler found an increase in group performance to a level above that of the individual performances. Kohler obtained comparable results from 3–person, and 4–person groups using the experimental procedure of weight lifting and winch turning. This phenomenon should be called the ‘Kohler effect’; although it is still to be replicated with modern ergometers.
