The purpose of this article, “I believe in order to love: Negative theology in the writings of St. John of the Cross”, is threefold. First we see how St. John uses classical negative theology as the basis of his spiritual programme. This is of especial interest because John manages to transform the theoretical method of apophatic discourse into a practical spiritual process. In this spiritual programme, discourse about God results in the soul’s refusal of the entire creation in an attempt to move closer to God through faith. This is particularly obvious in his metaphorical expression “the dark night”, which can be best interpreted in the light of Christ's passion, death and resurrection. The second purpose of this article is exactly to show how St. John uses the agony and pain of Christ as a model for the soul’s suffering in “the dark night”. Thirdly the aim is to put St. John’s negative theology in a contemporary and postmodern theological discourse and, in the light of this study, see if a new theological reading and understanding of it is possible

Vocal Communications and the Maintenance of Population Specific Songs in a Contact Zone

Bird song has been hypothesized to play a role in several important aspects of the biology of songbirds, including the generation of taxonomic diversity by speciation; however, the role that song plays in speciation within this group may be dependent upon the ability of populations to maintain population specific songs or calls in the face of gene flow and external cultural influences. Here, in an exploratory study, we construct a spatially explicit model of population movement to examine the consequences of secondary contact of populations singing distinct songs. We concentrate on two broad questions: 1) will population specific songs be maintained in a contact zone or will they be replaced by shared song, and 2) what spatial patterns in the distribution of songs may result from contact? We examine the effects of multiple factors including song-based mating preferences and movement probabilities, oblique versus paternal learning of song, and both cultural and genetic mutations. We find a variety of conditions under which population specific songs can be maintained, particularly when females have preferences for their population specific songs, and we document many distinct patterns of song distribution within the contact zone, including clines, banding, and mosaics
