Mennesket + husdyr = 90 prosent av alle pattedyr

Da mennesket for cirka 10.000 år siden begynte å dyrke jorden, begynte det også å temme husdyr. Bare målt i antall må husdyrene sies å ha hatt suksess med å bytte ut en vill natur med menneskets fjøs og beiteområder. Dagens raser omfatter milliarder av individer og utgjør 60 prosent av alle landpattedyr. Nå er 90 prosent av alle pattedyrene mennesker og husdyr, mens vi for 10.000 år siden utgjorde under 0,2 prosent.

Making the Garden — Christopher Alexander

Image
By Christopher Alexander . Original text at First Things . Rose trellis of Generalife. It has taken me almost fifty years to understand fully that there is a necessary connection between God and architecture, and that this connection is, in part, empirically verifiable. Further, I have come to the view that the sacredness of the physical world—and the potential of the physical world for sacredness—provides a powerful and surprising path towards understanding the existence of God, whatever God may be, as a necessary part of the reality of the universe. If we approach certain empirical questions about architecture in a proper manner, we will come to see God. It comes from realizing that the task of making and remaking the Earth—that which we sometimes call architecture—is at the core of any commonsense understanding of the divine. Only in the last twenty years has my understanding of this connection taken a definite form, and it continues to develop every day....

Tear Down the Corviale! New Urbanism Comes to Rome

Image
From the PLANETIZEN May 24, 2010 Nikos Salingaros presents the case for demolishing a modernist eyesore in Rome and replacing it with a high-density, mixed-use New Urbanist neighborhood. The Corviale building outside Rome is a social housing block that exemplifies the established Corbusian tradition of treating human beings as battery chickens. It was built during 1972-1982 as a single one-kilometer-long building. It is now estimated to house 6,000 people. Apologists who are nostalgic of Soviet-era social experiments continue to defend its paradigmatic modernist design on the grounds that every resident is EQUALLY oppressed in this inhuman environment, an ideal consistent with totalitarian notions of social equality. Apartments in the Corviale Building.

We are proposing tearing...

Raymond Ibrahim om Vesten og islam, katolsk fornyelse i Frankrike & kampen for skjønnheten

Stupetårnet i Engelandsvika må nok sies å være det flotteste bygget i Gjøvik i dette årtusenet. Diving tower from Lake Mjøsa by the town of Gjøvik in early June. Stock-bilde | Adobe Stock Nok en god samtale med Raymond Ibrahim, som er svært nyttig å ta med seg for vår tur til Frankrike, i kjølvannet av de islamske jihad-opptøyene i Paris nå i juni 2025. Denne fotballklubben er eid og sponset av Qatar, slik at i lys av hva Raymond forteller om jihad, er det klart det at Qatar bedriver jihad i Europas hovedstad. Målet er naturligvis at vår hovedstad skal erobres, i likhet med Konstantinopel, og at Notre Dame skal bli en moske, i likhet med Hagia Sofia. Islamic Appropriation at Mount Sinai: Egypt’s Assault on the World’s Oldest Continuously Functioning Christian Monastery Allikevel, som Raymond poengterer, må vi skille mellom muslimer og islam, da mange muslimer er flotte folk, på tross av denne politiske ideologien de har underkastet seg, da islam betyr underkastelse. Raymonds perspektiv...
