Sense of purpose

Sense of Purpose

According to Nobel Laureate, Robert William Fogel, we must have a sense of purpose in order to enjoy a life feeling fulfilled (see Citizendium article, The Fourth Great Awakening and the Future of Egalitarianism).

Fogel ranks sense of purpose first among a long list of non-material resources required for leading a rich life in terms of quality. To have a sense of purpose means that you have “something that one sets before himself as an object to be attained : an end or aim to be kept in view in any plan, measure, exertion, or operation”, and that you know that you have it (see ‘sense’ and ‘purpose’ in Webster's Third New International Dictionary, Unabridged. Merriam-Webster, 2002. http://unabridged.merriam-webster.com).

Because many of Citizendium’s volunteer authors write regularly and with enthusiasm, voluntarily and without byline-type credit*, I can only surmise that their doing so fulfills some inner need they have. It seems to me, after over five years with Citizendium, that their need falls into the broad category of pedagogy, sharing their knowledge with others, giving enrichment to the lives of others, a type of charity.

What they seem to get for themselves: the enrichment that comes with having a sense of purpose.

If all that seems a bit idealist, but not certainly so, try your own hand at sharing your knowledge through writing in Citizendium. You could also try doing it in some other free online wiki encyclopedia, like Wikipedia. Or try two or three and see which environment accords best with your sense of purpose.

What about popular culture:

History records that popular forms of entertainment have always existed. In his Historia, Herodotus (circa 485-425 BCE) wrote about amusing performances and songs that he encountered as he traveled the ancient world that seemed rather odd to him but that were highly popular. Fortunately, he thought, such phenomena were the exception, not the rule. Today's popular entertainment culture, or "pop culture" as it is commonly called, is instead the rule, not the exception. It is everywhere—on television, in movie theaters, in sport stadiums, in shopping malls, and so on. Is pop culture on the verge of taking over the hearts and minds of everyone living today?

Introduction

Consider this outline as an approach to defining ‘electric charge’:

• At one level of explanation of matter, matter consists of atoms.
• Electric charge is a property of matter manifesting in certain of the particle constituents of the atoms of matter.
• Studying atoms at the first level of their substructure, viz., the nucleus and surrounding electrons, can provide a fruitful starting point for explaining electric charge.

• As a starting point, note that:
  • Electrons can maintain their location surrounding and revolving about the nucleus only because a radial force of attraction on them exists directed toward the nucleus. Otherwise the electrons would fly off.

• Experiments reveal that:
  • The force of attraction between the nucleus and electrons greatly exceeds the gravitational force generated by the masses of the two groups of particles;
  • Therefore a force differing from the force of gravitation is operating, requiring a new designation;
    • For historical reasons discussed later, we designate the force an ‘electric force’.

...the electric force is approximately 42 orders of magnitude larger than the gravitational force. To see the enormity of this ratio, suppose that we represent the gravitational force by an arrow as long as a bacterium. How long would the length of the electric arrow be? Much larger than the height of a man; much taller than the Empire State Building; much larger than the Earth itself; much larger than the solar system; and much larger than the Milky Way. In fact, the electric arrow would be over 10 billion times larger than the "size" of the visible universe! That is why, when electrical forces are present, gravitational forces can be completely ignored.

• Experiments reveal also that:
  • The force of attraction occurs between the protons in the nucleus and the surrounding electrons, the two groups normally equal in number;
  • The magnitude of the electric force varies inversely with the square of the distance of separation over which the force operates.

• Experiments reveal also that:
  • The electric force between two spatially separate protons is one of repulsion rather than of attraction;
  • The electric force between two spatially separate electrons likewise is one of repulsion rather than of attraction;
  • When separated by the same distance, the magnitude of the electric force is the same between a proton and an electron, a proton and a proton, and an electron and an electron.

• Those experiments permit the conclusions that:
  • The electric force can be one either of attraction or repulsion;
  • Given that protons and electrons differ in mass by several orders of magnitude, the electric force does not depend on the masses of the interacting particles;
  • Therefore some quantitative property other than mass must generate and respond to the electric force between interacting particles;
    • call that property ‘electric charge’, and symbolize its unit of magnitude, q.
  • The ‘quality’ of the proton’s electric charge must differ from the ‘quality’ of the electron’s electric charge, otherwise protons and electrons could not generate and respond to either an attractive or repellent electric force depending on which interacts with which;
    • call the quality of the proton’s electric charge ‘positive’ and that of the electron’s ‘negative’, in keeping with historical designations arbitrarily assigned during the history of studies of electric phenomena on the macroscopic scale.

The convention was derived from Benjamin Franklin’s experiments. He rubbed a glass rod with silk and called the charges on the glass rod positive. He rubbed sealing wax with fur and called the charge on the sealing wax negative. Like charges repel and opposite charges attract each other.

• From the above discussion, we can formulate a provisional working definition of electric charge as follows:

Electric charge is a property of matter manifesting with an attribute of one or the other of two opposite extremes, arbitrarily referred to as positive and negative, a property of matter characteristic of certain of matter's constituent subatomic particles—specifically, protons (positive) and electrons (negative)—the property having the fundamental characteristic of producing and responding to a force of attraction between positive and negative particles, or of repulsion between positive and positive and between negative and negative particles, the force acting on spatially separated particles, that force, called the 'electric force', having a strength many orders of magnitude greater than that of the force of gravity, but like the gravitational, its strength falling in proportion to the square of the distance between the particles.

• Atoms of the chemical elements heavier than hydrogen...

Electric charge refers to a fundamental property of matter, a property upon which rests the numerous phenomena of electricity and electromagnetism, phenomena the particular provenance of science and engineering.

Electric charge manifests itself, in one guise, as a property of the two earliest discovered constituents of the historically conceived homogeneous and indivisible atom, namely, the subatomic particles, electrons and protons. The property of electric charge endows an electron and a proton, though spatially separate, with the ability to attract each other with a force of attraction, an electric force. The electric force of attraction between the proton and electron of a hydrogen atom gives the combination of the two charged particles its status as an atom, an atom of the chemical element, hydrogen, the lightest atom among those of all other chemical elements, whose atoms consist of more than one proton and electron.

The electric force of attraction between the two particles of the hydrogen atom differs from their gravitational force of attraction in that the magnitude of the electric force, for a given distance of separation of the two particles, exceeds by orders of magnitude the force of gravitational attraction between them associated with their masses, exceeding it ~10⁴² fold. For that reason, the force of attraction between an electron and a proton does not depend on the masses of the two particles, whose gravitational force can be ignored as a contributor to the magnitude of the attractive force.

...the electric force is approximately 42 orders of magnitude larger than the gravitational force. To see the enormity of this ratio, suppose that we represent the gravitational force by an arrow as long as a bacterium. How long would the length of the electric arrow be? Much larger than the height of a man; much taller than the Empire State Building; much larger than the Earth itself; much larger than the solar system; and much larger than the Milky Way. In fact, the electric arrow would be over 10 billion times larger than the "size" of the visible universe! That is why, when electrical forces are present, gravitational forces can be completely ignored.

For historical reasons, discussed subsequently, protons are said to be positively charged—i.e., to carry a positive electric charge—electrons, to be negatively charged—i.e., to carry a negative electric charge.

The convention was derived from Benjamin Franklin’s experiments. He rubbed a glass rod with silk and called the charges on the glass rod positive. He rubbed sealing wax with fur and called the charge on the sealing wax negative. Like charges repel and opposite charges attract each other.

A non-gravitationally-mediated force also exists between two spatially separate electrons, and between two spatially separate protons, but unlike the force of attraction between an electron and a proton, the force between two electrons is one of repulsion, as is the force between two protons. Thus the electric force can mediate electric attraction or repulsion, depending on the how the types of the charges compare, hence the common expression, “like charges repel, unlike charges attract”.

Experiments performed early in the 20th century established that the magnitude of the charge carried by the electron ("cathode ray corpuscle") equals that of the proton ("the positively charged hydrogen atom"), and that the former has a mass nearly 2000 times less than that of the latter. The magnitude of the electron charge, designated e, was formerly referred to as the 'elementary charge', the same for electrons and protons, despite their large mass difference. Since sensible matter consists collections of atoms, the magnitude of the net charge of a tangible substance must always be an integer multiple of e, the magnitude of the electron charge. For example, the net charge on the surface of a glass rod rubbed with a silk cloth will be positive, and the magnitude of that net charge will be an integer multiple of e, depending on the number of electrons stripped off the glass surface by the rubbing, which become attached to the surface of the silk cloth.

The terms 'positive' and 'negative' arbitrarily serve as labels to distinguish the two 'polarities', or opposing extremes, observed in the electric charge of matter. 'Positivity' and 'negativity' do not themselves imply anything about the fundamental nature of electric charge. Other labels connoting bi-polarity, such as yin/yang, black/white, or bitter/sweet, could have served for labeling, and but for historical chance, protons could carry a negative electric charge, electrons, a positive charge.

Scientists had established much of the above by the early 20th century, as evidenced from the discussion in first few chapters of the 1907 still instructively readable classic, The Corpuscular Theory of Matter, by the discoverer of the electron, Joseph John Thomson (1856-1940)

Once you have established those basic ideas about electricity, "like charges repel and unlike charges attract", then you have the foundation for electricity and can build from there. —Electric Charge, Hyperphysics Online

In reference to the physics and chemistry of electricity, charge, or more specifically, electric charge, is a fundamental property of matter that causes matter having that property to generate and react to a force of attraction or repulsion to spatially separate matter that likewise manifests the property of electric charge.

Whatever constitutes electric charge constitutes it as two separate qualities, or polarities, assigned the names 'positive' and 'negative', or 'plus' and 'minus'. The attractive force between electrically charged entities arises between oppositely-charged entities—positive-negative—whereas the repulsive force arises between like-charged entities—positive-positive, or negative-negative.

Familiar examples of positively charged matter are protons, constituents of the nuclei of atoms, and familiar examples of negatively charged matter are electrons, constituents of atoms that surround their nuclei.

Given that the terms 'positive' and 'negative' serve only as labels to distinguish the two polarities observed in the electric charge of matter, 'positivity' and 'negativity' do not themselves imply anything about the fundamental nature of electric charge. Other labels connoting bi-polarity, such as yin/yang, black/white, or bitter/sweet, could serve for labeling.

The atoms that comprise the chemical elements of the periodic table, while consisting in part of the electrically charged particles, protons and electrons, do not themselves manifest an electric charge, because protons in the nuclei and the surrounding electrons are equal in number and quantity of charge, that balance ensuring that the atoms as a whole manifest no net electric charge—a state referred to as electrical neutrality.

Discovery and naming of electric charge

The ancient Greeks as far back as the beginning of the 6th century BCE, beginning with Thales of Miletus, had observed some of the simple phenomenology related to electric charge, Thales demonstrating it using the fossilized tree resin, amber, rubbed with cloth:

That little piece of amber rubbed by Thales, some 2,500 years ago, appeared then to be very insignificant. Had the world but known, it was fraught with vast possibilities; for, in point of fact, Thales had unconsciously rediscovered Aladdin's Wonderful Lamp. As he rubbed, the Genie of electricity appeared, and demanded, "What wouldst thou have? I am ready to obey thee as the slave of the lamp, I and the other slaves of the lamp." But the question remained unanswered. Neither Thales nor the witnesses of his experiment made any request nor asked its genii to aid them. They had ears, but they heard not, and so the genie disappeared, with all that he was both willing and able to do left undone. —E.J. Houston, 1905

In 600 B.C. Thales, erudite philosopher and astronomer in the thriving Ionian port of Miletus, observed the special qualities of the rare yellow orange amber, jewel-like in its hardness and transparency. If rubbed briskly with a cloth, Thales showed, amber seemed to come alive, causing light objects—like feathers, straw, or leaves—to fly toward it, cling, and then gently detach and float away. Amber was similar to a magnet in its qualities, yet it was not a lodestone. As a youth, Thales of Miletus had studied in the sacred Egyptian cities of Memphis and Thebes. Perhaps it was there, under the burning sun, that this earliest of Greek philosophers first learned from the priests about the prized amber, with its seeming possession of a soul.

Thales, it appears, believed amber an animate thing, something with soul.

The Greek word for amber, elektron, ultimately through Latin, electrum, gave rise to the English words, electrical and electric — words used to refer to the amber phenomenon before the publication of William Gilbert's landmark work, De magnete, in 1600, describing the results of the first systematic experimental studies of magnetic and electrical phenomena in Western science.

The word, charge, used in its electrical sense, was first used by Benjamin Franklin, in 1747, as a verb, and subsequently by him as adjective and noun:

Our spheres are fixed on iron axes, which is passed through them. At one and of the axis there is a small handle, with which you turn the sphere like a common grindstone. This we find very commodious, as the machine takes up little room, is portable, and may be enclosed in a tight box, when not in use. 'Tis true, the sphere does not turn so swift as when the great wheel is used, but swiftness we think of little importance, since a few turns will charge the phial, etc., sufficiently. [italics added]

Presumably, Franklin, who, in his many writings, frequently used the word, charge, and its variant forms (charging, charged, etc.), in its non-electrical sense, had in mind the word's sense of 'loading' or 'filling' something:

charge - ORIGIN: Middle English (in the general senses ‘to load’ and ‘a load’): from Old French charger (verb), charge (noun), from late Latin carricare, carcare ‘to load,’ from Latin carrus ‘wheeled vehicle.’...Examples: load or fill (a container, gun, etc.) to the full or proper extent: will you see to it that your glasses are charged? | fill or pervade (something) with a quality or emotion: the air was charged with menace.

For lede Evolutionary linguistics

Some of the core questions in evolutionary linguistics are stated on the website of the linguistics department of the University of California, Santa Barbara:

Since spoken language does not leave any fossil record, the study of the origin and evolution of language is necessarily inferential on the basis of cross-disciplinary understanding of linguistics, neuroscience, paleoanthropology, molecular genetics, and animal cognition/communication. Of particular significance are those hominid behaviors that cannot take place without linguistic communication. A surprising issue that rises from this cross-disciplinary research is the nature of language. In the continuum of the evolutionary development of human cognition and behavior adduced from the paleoanthropological records, when did hominid communication qualify as “language”? 0*Would the emergence of symbolic signals mark the beginning of language? Was the appearance of the first symbolic signal among hominids the watershed event that led instantly to a cascade of new symbolic communicative signals within a few generations, or was the increase of symbolic signals a gradual process on an evolutionary time scale in accordance with the evolution of cognition? Is there a “critical mass” of symbolic communicative signals that is necessary to trigger the development of grammar? Did grammar emerge gradually on an evolutionary scale of time, contrary to the fast-paced emergence of grammar in pidginization and creolization?

There are many others, as will become apparent in this article.

Philosophers of mind, and all those scholars of myriad disciplines who have given serious inquiry into the nature of mind, have not agreed upon a definition of conscious experience, or ‘consciousness’, the term commonly used to refer to conscious experience. To quote a leading philosopher of mind, David Chalmers:

There is nothing that we know more intimately than conscious experience, but there is nothing that is harder to explain.

Nicholas Humphrey, another leading philosopher of mind, elaborates:

The hard problem is to explain how an entity made entirely of physical matter—such as a human being—can experience conscious feelings. The problem is hard because such feelings appear to us, who are the subjects of them, to have properties that could not possibly be conjured out of matter alone.

Philosopher of mind, David Rosenthal, gives the following definition(s):

The term 'consciousnes' is used in several ways: to describe a person or other creature as being awake and sentient, to describe a person or other creature as being 'aware of' something, and to refer to a property of mental states, such as perceiving, feeling, and thinking, that distinguishes those states from unconscious mental states.

Philosopher of mind, Bernard Baars, asks us to consider this:

Our standard behavioral index for consciousness is the ability people have to report their experiences, often in ways that can be checked for accuracy.…... Under well-defined condition, such reports are exquisitely sensitive.… Conscious processes can be operationally defined as events that: (1) can be reported and acted upon, (2) with verifiable accuracy, (3) under optimal reporting conditions, (4) and which are reported as conscious.
