Descriptions and explanations

Lavoisier

An example will illustrate the difference between these two concepts:

• Antoine-Laurent de Lavoisier is considered the father of modern chemistry. His Traité Élémentaire de Chimie revolutionized many of the ideas that until then had dominated this science. However, when it comes to the chemical reactions it describes, this book is a mere catalogue. So we are told something like this:

If we mix oxygen gas and hydrogen gas and apply fire or an electric spark to the mixture, an explosion occurs and the result is water.

This is a description. It tells what happens but offers no explanation of the phenomenon.

Exploration of the solar system in science fiction

The exploration of the solar system is one of the classic themes of science fiction, although it is surpassed by the exploration of the galaxy, both in the number of works and in the variety of arguments to which it has given rise.

Among my favorite works on this subject I will cite the following:

• Exploration and colonization of the moon. Two novels that make a series: De la Terre à la Lune and Autour de la Lune by Jules Verne, whose protagonists circumambulate the moon, but are unable to land; and two short stories: The Singing Bell by Isaac Asimov and The Menace from Earth by Robert Heinlein. In the second there is a well-established base on the moon.

Richard Dawkins versus John Lennox

Richard Dawkins

At the age of fifteen I wrote my first book, with no intention of publishing, just for my personal use. It was a two-volume zoology of invertebrates. I still refer to it, although classifications have changed a lot, with the rise of cladistics and DNA analysis.

In 1977, this time with the intention of sending it to the printer, I wrote another book in English under the title Human cultures and evolution, where I proposed the following:

·         Cultural evolution is equivalent to biological evolution. Many properties are common to both fields. Human civilizations are equivalent to biological species and describe similar life curves. There is a cultural selection, equivalent to and very similar to natural selection, proposed by Darwin to explain the origin of the species.

Transhumanism, is it possible?

First, we must differentiate three different concepts:

a)   Technological singularity: the apparently exponential increase of our technological advances will tend to infinity in a very short time. By then, anything we may want to do, will be possible.

b)  Transhumanism: the amelioration of the human species by means of technology.

c)   Posthumanism: the generation of a new species as a hybrid of human beings and technology.
