“Death is Nothing to Us”

Death is inevitable. What it entails is largely unknown. Some believe that it permanently ends an individual’s existence; others that it simply provides a transition to another form of life. Most people fear it, but some consider it with equanimity. Among the latter are the followers of Epicurus, who claimed

Death is nothing to us. For what has been dissolved has no sense-experience, and what has no sense-experience is nothing to us.
(Epicurus, reported by Diogenes Laertius, translated by Inwood and Gerson, 1997, p 32; another translation is by Yonge, 1983, p. 474).

Epicurus proposed that human beings are made of complex compounds of atoms. At death these compounds dissolve, releasing the atoms to form other things. The body decays and the soul evaporates. Once we are dead, we are no more. We cannot feel what it is like to be dead. And the dead certainly cannot experience pain. Death should therefore not be feared.

Epicureanism was popular during the Roman period. A common Latin epitaph summarized the life of the Epicurean as a brief interlude between the nothingness preceding birth and the nothingness following death:

          Non fui, fui, non sum, non curo
          (I was not; I was; I am not; I do not care).

Modern Wheels

The wheel has been around since about 4000 BCE (Bulliet, 2016). The first wheels used for transportation may have derived from potters’ wheels used for moulding cups and bowls. Some early wheels were made of stone, but these were soon replaced by wood which was lighter and faster. Around 3000 BCE spokes were invented, and for several thousand years fast-moving chariots with spoked wheels often decided ancient battles.  

By the middle of the nineteenth century wooden wheels for carts and carriages had become fully developed (see figure). The rim was made by bending ash to form curved felloes. These were attached to the hub by strong oak spokes, and held in place by a steel tire. 

In the last two hundred years the wheel has changed dramatically. Some changes have made the wheels more efficient (working well) and some made them more attractive (looking lovely). The forces driving the changes are thus similar to those that occur during evolution with its survival of the fittest and its sexual selection. However, wheel innovation is controlled by human design rather than random mutation, and the changes have occurred much more rapidly. And, as in evolution, some innovations do not survive: hubcaps and whitewall tires have become extinct.

Music of the Viola

The viola is much under-rated. The instrument is difficult to play and its sound box is not optimal for its range of notes. Violists are the butt of numerous jokes maligning their tuning and their timing. Nevertheless, in the hands of a master, the viola has a wonderfully rich sound, melancholy in its low register and silvery in the high. Of all the strings it is perhaps most similar to the normal human voice.

Stones of the Picts

With my surname it is inevitable that I should become interested in the Picts, a people who lived in Scotland during the first millennium of the Common Era. They left behind many sculptured stones, which now stand in fields and churchyards in the Northeast part of Scotland. Together with the Scots, the Vikings and the Anglo-Saxons, they became the people of Scotland.

Mitchell and Riopelle

From February 18 to May 6, 2018, the Art Gallery of Ontario (AGO) is presenting an exhibition of the paintings of Joan Mitchell and Jean-Paul Riopelle entitled Mitchell/Riopelle: Nothing in Moderation. This is the first time that many of these paintings have been seen together. The paintings are stunning, the relations between them fascinating.

The Mysteries

For over a millennium the Mysteries were celebrated at Eleusis, about 18 km northwest of Athens. The main buildings in the temple precinct were built in the 5th Century BCE, but earlier buildings were present in the 6th Century, and evidence of cult-activity at the site goes back to the Mycenaean period before 1100 BCE (Mylonas, 1961, Chapter II). The Mysteries continued through the Hellenistic and Roman ages until their demise in the 4th Century CE when Christianity became the dominant religion of the Roman Empire.

What happened during the Mysteries is unknown. Those who were initiated into the Mysteries were instructed not to reveal their secrets. All we know is that they provided their initiates with a vision of the divine and a way to cope with death.

Aspects of Etruria

 

The Etruscans thrived from about 900 to 100 BCE. Although archaeology has revealed much about their life, even more remains unknown. After the Etruscans were assimilated by the Romans, their written history was lost. Although the Emperor Claudius wrote a 20-volume history of the Etruscans, not a page of this has survived.

Popular ideas that the Etruscans originated in Greece, Turkey or Phoenicia have given way to the idea that they were indigenous to the area where they lived – Etruria. This is the land north of the Tiber River, south of the Po River and west of the Apennine Mountains, comprising the present day Italian regions of Lazio, Tuscany and Umbria.

Stonehenge

Over five thousand years ago the Neolithic people of Britain began to erect a monumental stone structure known as “Stonehenge” on the Salisbury Plain. The name likely means “hanging” or “suspended” stones. The structure underwent several changes over the years of its construction, reaching its final form around 2000 BCE.

The stones are of two kinds. The largest are the sarsens, which have their origin in the hills about 40 km north of Stonehenge. The word “sarsen,” first used at the time of the Crusades, comes from “Saracen” and essentially means “pagan.”

The smaller bluestones come from the Preseli Mountains in Southwest Wales 240 km away. Most archaeologists currently believe that these were transported across the Bristol Channel and then overland to Stonehenge. The bluestones may have been used in several ways during the different periods of construction. In the final form of the monument they are arranged within the outer circle of sarsens and within the inner horseshoe of larger sarsens.

The monument has long been a symbol of ancient Britain. Over the years, however, our understanding of it has changed radically. This posting considers how Stonehenge has interacted with the British imagination. Because of its striking appearance, images are given as much space as words.

Divine Geometry

 

The Counter-Reformation, initiated by the Council of Trent (1545-1563) in response to the Protestant Reformation, promoted art as a way for believers to become emotionally involved in the Church. While Protestants were whitewashing church walls and destroying sculptures, Catholics produced the masterpieces of Baroque Art. For the Protestant, nothing should come between man and God; for the Catholic, the majesty of art could bring man to the mystery of God.

Human Brain

Over the past two months I presented a course on the Human Brain to students in the LIFE (‘Learning is Forever’) Institute at Ryerson University in Toronto. The course was designed for the senior layperson. It introduced the basic anatomy and physiology of the nervous system, and described the various disorders that can affect the elderly human brain.

The course was given at a second-year university level. Some of the material may have been more than the students needed to know, but most were able to follow the main points of the talks, and some were fascinated by the details.

The presentations were supplemented with extensive teaching materials – slides, notes, movies, etc. Many of the illustrations were adapted or created specifically for the course. I am now making these generally available through the page entitled Human Brain on my website.
