Yaqeen Institute for Islamic Research 3 | Mindfulness in the Life of a Muslim Introduction In the name of Allah, the Gracious, the Merciful Modern life involves a daily bustle of noise, distraction, and information overload. Our senses are constantly stimulated from every direction to the point that a simple moment of quiet stillness seems impossible for some of us. This continuous agitation hinders us from getting the most out of each moment, subtracting from the quality of our prayers and our ability to remember Allah. We all know that we need more presence in prayer, more control over our wandering minds and desires. But what exactly can we do achieve this? How can we become more mindful in all aspects of our lives, spiritual and temporal? That is where the practice of exercising mindfulness, in the Islamic context of muraqabah, can help train our minds to become more disciplined and can thereby enhance our regular worship and daily activities. -
Lecture 20 - the History of Life on Earth
Lecture 20 - The History of Life on Earth Lecture 20 The History of Life on Earth Astronomy 141 – Autumn 2012 This lecture reviews the history of life on Earth. Rapid diversification of anaerobic prokaryotes during the Proterozoic Eon Emergence of Photosynthesis and the rise of O2 in the Earth’s atmosphere. Rise of Eukaryotes and the Cambrian Explosion in biodiversity at the start of the Phanerozoic Eon Colonization of land first by plants, then by animals Emergence of primates, then hominids, then humans. A brief digression on notation: “ya” = “years ago” Introduce a simple compact notation for writing the length of time before the present day. For example: “3.5 Billion years ago” “454 Million years ago” Gya = “giga-years ago”, hence 3.5 Gya = 3.5 Billion years ago Mya = “mega-years ago”, hence 454 Mya = 454 Million years ago [Note: some sources use Ga and Ma] Astronomy 141 - Winter 2012 1 Lecture 20 - The History of Life on Earth The four Eons of geological time. Hadean: 4.5 – 3.8 Gya: Formation, oceans & atmosphere Archaean: 3.8 – 2.5 Gya: Stromatolites & fossil bacteria Proterozoic: 2.5 Gya – 454 Mya: Eukarya and Oxygen Phanerozoic: since 454 Mya: Rise of plant and animal life The Archaean Eon began with the end of heavy bombardment ~3.8 Gya. Conditions stabilized. Oceans, but no O2 in the atmosphere. Stromatolites appear in the geological record ~3.5 Gya and thrived for >1 Billion years Rise of anaerobic microbes in the deep ocean & shores using Chemosynthesis. Time of rapid diversification of life driven by Natural Selection. -

It’s how nature creates itself, on every scale, the snowflake and the snowstorm. — TOM STOPPARD, Arcadia, Act 1, Scene 4 (1993) Much has been written about evolution from the perspective of the history and biology of animals, but significantly less has been writ- ten about the evolutionary biology of plants. Zoocentricism in the biological literature is understandable to some extent because we are after all animals and not plants and because our self- interest is not entirely egotistical, since no biologist can deny the fact that animals have played significant and important roles as the actors on the stage of evolution come and go. The nearly romantic fascination with di- nosaurs and what caused their extinction is understandable, even though we should be equally fascinated with the monarchs of the Carboniferous, the tree lycopods and calamites, and with what caused their extinction (fig. 0.1). Yet, it must be understood that plants are as fascinating as animals, and that they are just as important to the study of biology in general and to understanding evolutionary theory in particular. -
Human Nature Must Be Disengaged
THE WELL-SPRINGS OF ACTION: AN ENQUI RV INTO '1-l.M\N NATIJRE' I Richard Broxton Onians' (1951) book, The Opigins of European Thought about the Body, the Mind, the SouZ, the WopZd, Time and Fate, is as exhaustive as the title suggests. Its value rests in enabling us to perceive the dim outlines of a theory of human powers which was present in the minds of the peoples of western Europe before the dawn of history. The phenomenology and osteol ogy with which Onians supplemented the. account, further enable us to locate the physiological processes on which the theory must have been based. It has been lost. Today we possess only fragments. And yet,we repeatedly make recourse to the theory in our behaviours and speech as if we knew its substance. The hand is placed upon the chest when one pledges allegiance to one's country. To indicate assent, one nods one's head. Some one who is over-sexed is called 'horny'. In a Catholic church, one touches one's forehead and one genuflects before the altar. We associate the symbol of a skull and crossbones with death. We ascribe to ourselves the capacity of appreciating the 'aesthetics' of an object, and speak of the inspiration we receive from a speech. These are but 'shreds and patches', but at one point they were connected. The theory rested on a primordial disjunction between fluid and air; between the liquid or liquefiable substances con tained in the brain, the cerebro-spinal column, the genitals and joints, and the breath. -

The Evolution of Life
Study Guide # 2 - Spring, 2000 Geology 230 - Evolution of the Earth THE EVOLUTION OF LIFE Lynn S. Fichter James Madison University Topics to be covered and general objectives: During this period, we will cover the following topics in lecture: ( The record of life on earth. Are there recognizable patterns, or is it all just random and unpredictable? " An introduction to non-equilibrium thermodynamics (chaos/complexity theories). " Evolution of Moneran biochemical pathways. " Symbiosis and the origin of the Protist kingdom. " The Origin of multicellularity. " The Phanerozoic record of multicellular life. ( A sampling of the significant scientific problems in the history of life on earth. Just how much do we know and understand after more than a century of study? " The principles of non-equilibrium thermodynamics [Prigogine's Dissipative Structures and Bronowski's Stratified Stabilities]. How can life get more complex when the second law of thermodynamics says everything in the universe should be running down? " Evolutionary Theory. Many problems exist in science which are very difficult to solve, and which do not have simple solutions. Evolutionary theory is much more than Darwin's theory of natural selection. " The Gaia hypothesis for the coevolution of life and the earth. To what degree are the Earth and life related? PROCESS #1 "Any phenomenon which shows continuous change in time"; #2 "A series of actions or operations definitely conducing to an end." GEOLOGY 230 STUDY GUIDE: THE EVOLUTION OF LIFE SPRING SEMESTER, 2000 - 2 Theory-free science makes about as much sense as value-free politics. Both terms are oxymoronic. All thinking about the natural world must be informed by theory, whether or not we articulate our preferred structure of explanation to ourselves. -
“Politics” and “Religion” in the Upper Paleolithic: a Voegelinian Analysis of Some Selected Problems
“Politics” and “Religion” in the Upper Paleolithic: A Voegelinian Analysis of Some Selected Problems DRAFT ONLY Barry Cooper University of Calgary Paper prepared for APSA Annual Meeting Seattle WA September, 201 2 Outline 1. Introduction 2. Philosophy of consciousness 3. “Politics” 4. “Religion 5. Conclusions 3 “Politics” and “Religion” in the Upper Paleolithic 1. Introduction The Voegelinian analysis referred to in the title refers primarily to two elements of the political science of Eric Voegelin. The first is his philosophy of consciousness, systematically developed first in Anamnesis.1 The second is his concept of compactness and differentiation of experience and symbolization. It will be necessary to touch upon a few other Voegelinian concepts, notably his understanding of “equivalence,” but for reasons of space only a summary presentation is possible. A second preliminary remark: the terms “Religion” and “Politics” are in quotation marks because their usage in the context of the Upper Paleolithic is anachronistic, though not entirely misleading. The meaning of these terms is commonsensical, not technical, and is meant to indicate what Clifford Geertz once called “oblique family-resemblance connections” among phenomena.2 Third, as a matter of chronology the Upper Paleolithic conventionally refers to the period between 50,000 and 10,000 years ago (50KYBP- 1 Voegelin refined his analysis of consciousness in the last two volumes of Order and History. These changes are ignored on this occasion. 2 Geertz, Life Among the Anthros, ed. Fred Inglis (Princeton: Princeton University Press, 2010), 224. 4 10KYBP).

Natural Reward Drives the Advancement of Life
Rethinking Ecology 5: 1–35 (2020) doi: 10.3897/rethinkingecology.5.58518 PERSPECTIVES http://rethinkingecology.pensoft.net Natural reward drives the advancement of life Owen M. Gilbert1 1 University of Texas at Austin, Austin, USA Corresponding author: Owen Gilbert ([email protected]) Academic editor: S. Boyer | Received 10 September 2020 | Accepted 10 November 2020 | Published 27 November 2020 Citation: Gilbert OM (2020) Natural reward drives the advancement of life. Rethinking Ecology 5: 1–35. https://doi. org/10.3897/rethinkingecology.5.58518 Abstract Throughout the history of life on earth, rare and complex innovations have periodically increased the efficiency with which abiotic free energy and biotic resources are converted to biomass and organismal diversity. Such macroevolutionary expansions have increased the total amount of abiotic free energy uti- lized by life and shaped the earth’s ecosystems. Meanwhile, Darwin’s theory of natural selection assumes a historical, worldwide state of effective resource limitation, which could not possibly be true if life evolved from one or a few original ancestors. In this paper, I analyze the self-contradiction in Darwin’s theory that comes from viewing the world and universe as effectively resource limited. I then extend evolutionary theory to include a second deterministic evolutionary force, natural reward. Natural reward operates on complex inventions produced by natural selection and is analogous to the reward for innovation in human economic systems. I hypothesize that natural reward, when combined with climate change and extinction, leads to the increased innovativeness, or what I call the advancement, of life with time. I then discuss ap- plications of the theory of natural reward to the evolution of evolvability, the apparent sudden appearance of new forms in the fossil record, and human economic evolution.
