Some Remarks on the Concept of Toleration

The paper contains a conceptual analysis of "act of toleration" and the property of "being tolerant". Being tolerant is understood as a dispositional property of persons manifested in what the author calls the "circumstances of toleration". The main circumstances distinguished are: a tendency to prohibit a certain behaviour and the competence to determine the deontic status of the behaviour in question. An act of toleration, then, consists in not prohibiting (or cancelling the prohibition of) that behaviour. It is argued that this requires the existence of two different normative systems, the "basic system", and the "justifying system". Acts of toleration must be based on reasons coming from the latter. This insight enables one to establish a difference between reasonable and unreasonable toleration, as well as between toleration and related concepts like indifference, acquiescence, etc. The analysis also introduces the distinction between "vertical" and "horizontal" toleration. Acceptance of this last category implies that toleration does not necessarily require hierarchical relationships between those who tolerate and those whose actions are tolerated.     

Identification and Individualization of Lophophora using DNA Analysis of the trnL/trnF Region and rbcL Gene

Lophophora williamsii (peyote) is a small, spineless, greenish‐blue cactus found in Mexico and the southwestern United States. Ingestion of the cactus can result in hallucinations due to its content of mescaline. In the United States, L. williamsii is classified as a Schedule I controlled substance. In this study, we use DNA analysis of the chloroplast trnL/trnF region and chloroplast rbcL gene to identify the individuals of Lophophora. Using the rbcL gene, Lophophora specimens could be distinguished from outgroups, but species within the genus could not be distinguished. The trnL/trnF region split the Lophophora genus into several groups based on the length and substructure of an AT‐rich segment of the sequence. Our results indicate that the genetic variability at the trnL/trnF locus is greater than previously recognized. Although DNA structures at the trnL/trnF region and rbcL gene do not align with the classification of Lophophora species, they can be used to aid in forensic analysis.
