Many a beautiful plant cultivated to deformity, and arranged in strict geometrical beds, the whole pretty affair a laborious failure side by side with divine beauty.A Thousand-Mile Walk to the Gulf is the second book in John Muirs Wilderness-Discovery series. It is within this work that we are really given strong clues toward Muirs future trailblazing movement for environmental conservation, in such comments as The universe would be incomplete without man; but it would also be incomplete without the smallest transmicroscopic creature that dwells beyond our conceitful eyes and knowledge.Muirs walk from Indiana to Florida was conceived in order to explore and study further the flora and fauna across states. He undertakes this alone, a dangerous choice perhaps so soon after the civil war, as many characters along the way forewarn. Indeed, Muir is threatened by a robber, and we see a new side to the quiet, lowly gentleman we know as he springs into self-defence mode with lightning initiative and remarkable courage.This is not the only facet of Muirs personality that is uncovered throughout this journey. He makes reference to feeling dreadfully lonesome and poor, which is intriguing as his circumstances are self-sought: Stayed with lots of different people but preferred sleeping outside alone where possible. He spends a substantial period of time struck down with malaria, which does not come as a surprise; he was covering many miles on an unsustainably meagre diet with thirst often quenched with swamp water or not at all.Join Muir in Kentucky forests, Cumberland mountains, Florida swamps and all the elegantly described trees, plants, creatures and rocks in-between. A Thousand-Mile Walk to the Gulf teaches us as much about Muir himself as it does the ecosystems in the wilderness across those 1,000 miles.

Este libro es especialmente necesario en este 2021 raro en el que la pandemia y el consiguiente confinamiento nos han obligado a todos y todas a encerrarnos en nuestras casas impidiéndonos, no ya solo conocer a nadie en carne y hueso, sino incluso mantener algun tipo de contacto tactil. Sin embargo, ese contacto humano, esa necesidad de amar, de sentir algo, de emocionarnos, de desear y de que nos deseen; ese aburrimiento que se nos apodera cuando nuestro corazon esta impasible; esa soledad que se apodera del alma sobre todo por las noches todas esas emociones a veces desoladoras nos empujan a buscar remedio a traves de las pantallas que tenemos tan a mano. Y lo mismo le mandamos mensajitos a toda la red de examantes del pasado para tantear, que nos creamos un perfil en Adoptauntio.com o en Tinder o Grindr para ver que se ofrecen los demas usuarios que se sienten igual de aislados y solos, pero con ganas de animarse un poco emocional y sexualmente. ¿Que ocurre?

Personas que son capaces de saltar de unas victimas en otras y huir en cuanto se plantea la posibilidad de una relacion de verdad. Vamos a profundizar en ello para ir bien pertrechados y protegidas ante esta nueva forma de relacionarse que tantas heridas puede dejar.

Geoffrey Chaucer, born in London most likely around 1340, was an English poet, author, philosopher, scientist, diplomat and politician. He has been called the father of English literature, or, alternatively, the father of English poetry, but he should be considered, in a broader sense, for the breadth of his interests and the richness of his works, the father of English Humanism.He is seen as crucial in legitimising the literary use of Middle English when the dominant literary languages in England were still Anglo-Norman French and Latin.Parallel to his activity as a prolific writer, he maintained a career in the civil service as a bureaucrat, courtier, diplomat, comptroller of the customs for the port of London and member of parliament.Chaucers Treatise on the Astrolabe, addressed in 1391 to his ten old son Lowys, is considered the oldest work in English written upon an elaborate scientific instrument or the first example of technical writing in the English language. It describes the form and use of the astrolabe in detail and it indicates that Chaucer was versed in science in addition to his literary and philosophical talents.With a preface by Boris Yousef.
