The Man’s Experience of Life in the Natural World
What it is to be a Substance? and What it is to Exist? We need to establish knowledge about the man on a firm basis and the information it provides must be tested for its accuracy and consistency with an external reality. We have to make the fundamental distinction between the living and the non-living matter. The scientific advances of the 19th and 20th centuries reinforced the materialistic position concerning the basic similarity of organic living and inorganic physical matter. The man is viewed as a product of natural evolution and is thought to be subject to the same laws of Physics and Chemistry or mechanistic principles.
We need a methodology to study philosophy and to understand philosophical statements. Logical Positivism, also known as Scientific Empiricism aims to clarify concepts in both everyday and scientific language. It describes analysis of language as the function of philosophy. This analysis of language and of concepts is important to understand questions of belief and ideology which affect what we think we ought to do individually and socially. I would use this method of ‘Applied Philosophy’ to analyze the concept of Spiritual Optics, the Spiritual dimension of the Man’s experience of Life in the Natural World.
The Beginning. The Story of Creation
The Holy Bible, The Old Testament, Book of Genesis, Chapter 1 (verses 1,3,4,5,14 and 15) describes the creation of day and night.
In the beginning God created the heavens and the earth.
And God said, “Let there be light,” and there was light.
God saw that the light was good, and He separated the light from the darkness.
God called the light “day,” and the darkness He called “night.” And there was evening, and there was morning – the first day.
And God said, “Let there be lights in the expanse of the sky to separate the day from the night, and let them serve as signs to mark seasons and days and years, and let them be lights in the expanse of the sky to give light on the earth.”
Explanation: How does your favorite planet spin? Does it spin rapidly around a nearly vertical axis, or horizontally, or backwards? The featured video animates NASA images of all eight planets in our Solar System to show them spinning side-by-side for an easy comparison. In the time-lapse video, a day on Earth — one Earth rotation — takes just a few seconds. Jupiter rotates the fastest, while Venus spins not only the slowest (can you see it?), but backwards. The inner rocky planets, across the top, most certainly underwent dramatic spin-altering collisions during the early days of the Solar System. The reasons why planets spin and tilt as they do remains a topic of research with much insight gained from modern computer modeling and the recent discovery and analysis of hundreds of exoplanets: planets orbiting other stars.
Different planets have different rates of rotation. We use Earth’s spin to define coordinate systems for locating objects both on the ground and the sky. The timekeeping system that we use is related to the rotation of the Earth. My human existence in this Universe is synchronized with the rotational spin of the Earth. The spin gives me alternating periods of light and darkness known as Day and Night while the Sun is shining all the time.
Synchronization of the External and Internal Environment of the Living Things
The Biological Clock – Every living system studied behaves as if it contains a highly dependable clock. The specialized properties of this clock suggest that it involves some unique biological mechanism indissociable from life itself.
The Biological Clock is a self-sustained internal timing mechanism that controls cyclic patterns, or rhythms, of a living organism. All organisms have this ability to synchronize their existence to events in both their internal or external environment. Because of this internal timing, certain physiological and behavioural events vary in intensity. Such time-dependent variability is expressed as a rhythm, or oscillation, with a frequency equal to that of the underlying biological clock. Biological clocks time the Solar day, the period of the Earth’s rotation relative to the Sun.
The Biological Rhythm – Biological Rhythms represent the periodic biological fluctuation in an organism that corresponds to and is in response to periodic environmental change. The most important example of such environmental change is that of the cyclical variations in the relative position of the Earth to the Sun and the immediate effect of this variation is that of night alternating with day or the change from darkness to light. Biological Rhythms that occur once a day are called Circadian(Latin circa:”about,” di: “day,”), Solar day, diel, daily, diurnal(day-active), or nycthemeral rhythm. Circadian rhythms are the most pervasive rhythms regulating many events for every day in the lives of most living organisms. Circadian rhythms are synchronized to an external time-giving stimulus. The external stimulus that is important for most living organisms is that of Sun rise and Sun set, the daily light-dark cycle determined by Earth’s rotation.
The Day Active or Diurnal Rhythm Regulating the Man
Within the 24-hour cycle(circadian), a person usually sleeps approximately 8 hours and is awake 16 hours. In man, the daily alteration of sleep and wakefulness is accompanied by many changes, including activities of the nervous and endocrine systems and the liver and kidneys. Daily variations occur in body temperature, in heart and respiratory rates, and in blood pressure and composition of the blood.There are daily variations in chemical syntheses and in cell divisions.
During the wakeful hours, mental and physical functions are most active and tissue-cell growth increases. During sleep, voluntary muscle activities nearly disappear and there is a decrease in metabolic rate, respiration, heart rate, and blood pressure. The activity of digestive system increases during the resting period, but that of the urinary system decreases. Hormones secreted by the body, such as the stimulant epinephrine(adrenaline) are released in maximal amounts about two hours before awakening so that the body is prepared for activity.
If a person tries to break the circadian rhythm by ignoring sleep for a number of days, psychological disorders begin to arise.
The Laws of Nature
Diverse aspects of human physiology and behaviour show that human existence is synchronized with the Laws of Nature. When we live in accordance with the law, we get a chance to know the provider of the law.
