Do we know what matter is?


Matter is at the same time something very mundane and incredibly complex. We deal with material objects all the time and jet when we are press to define what matter is, we end up with a unsatisfactory answer like “matter is that of which things are made of”. And then we can give examples of different materials (type of matter): steel, water, soil, rock, air,…

Our understanding of matter has changed a lot over the last century with new scientific insights, but much is still debated, many of the positions defended have a long history at their backs. This topic has been a central issue of philosophy for over 2000 years, clearly a lot of though has gone into the matter.

Philosophical understanding of matter

Matter has been a topic of great discussion from the time of the Greeks, and still is central debate between religious people, who in some way or other believe on the existence of non-material, let’s say spiritual, things and atheist or materialists who state that matter is all that exist.

The discussion of the essence of matter in ancient Greeks

The ancient Greek thought matter was formed by mixing 4 elements: water, air, fire and earth. Different materials from wood to iron and gold were thought to be mixtures on different percentages of the four basic elements. Thales of Miletus thought the first principle was water, this came from the observation that there is moisture everywhere so water is par of everything. His pupil Anaximander said that water couldn’t be the first, principia, since water couldn’t produce fire, the same happened with the other elements, non were able to create their opposite, thus there was no principal element as such. He nonetheless proposed a perfect, unlimited, eternal and indefinite substance, the Aperion, from which all was created. Anaximenes, Anaximandres pupil, returned to the elemental principia, theory but proposed air as the original element from which everything else is created. He said that though rarification air produced fire and through compression water and subsequently earth.

Pythagoras of Samos said that numbers not matter were the origin of everything. Heraclitus said that no matter was possible since all in life is flux and continuous change. On the other hand Parmenides believed that the universe was static and the hold the only truth, our senses however were changing and unreliable, rendering knowledge of truth impossible. Leucippus and Democritus held that matter was composed of indivisible constituents, atoms. As one can see there was a long debate of what matter was even as far back as the 6th century before Christ.

John Dalton discovered the atom in 1803, giving evidence towards the views held by Leucippus and Democrates.

Modern philosophy: idealism and materialism

The Idealism movement is a group of thinkers which held that reality is principally mental, all we know of the world is what our mind interprets of the world in itself which is out of our reach. The most well known of these thinkers are: Immanuel Kant, G. W. F. Hegel and A. Schopenhauer. In their theories matter is relegated to a secondary place since the world is basically immaterial, or at least our knowledge of the universe is strongly conditioned by our mental process meaning the original essence of matter is not critical since all we ever have a chance to know is mental.

On the opposite side the materialism is a form of philosophical monism which holds that matter is the fundamental substance in nature, and that all phenomena, including mental phenomena and consciousness, are results of material interactions.

There are other philosophical theories that fall in dualistic or pluralistic reality, meaning the world is not purely mental, spiritual or material but is a composition of 2 or more aspects. Descartes is probably one the best known representative of the dualistic nature of reality.


Scientific understanding of matter

From a scientific perspective in classical mechanics a material object is characterized with a position in space and time and some physical properties like volume and mass. All of these properties of matter have a very specific definition and meaning but the only definition of matter that will extract from mechanics is: “matter is that which lays on a position in space and time and occupies a volume and has mass” .

If we go further into quantum and relativistic mechanics we find that ordinary matter is structured, formed by atoms which themselves are composed of particles: electrons , neutrons and protons. neutrons and protons are also composite particles each consisting of 3 quarks. Other more exotic forms of matter exist, formed by all sorts of particles: muons, tauons, neutrinos (3 flavous), mesons (formed by a quark anti quark pair)… In addition we know from relativity that mass and energy are really part of the same thing so massless particles like photons also qualify as matter. From this perspective matter is formed from a sea of particles which in turn are just things that occupy a position in spacetime and have some physical properties like mass, electric charge and spin.

Particles on the standard model of physics.

As we can see science is good at telling us the structure of matter, which are its constructive blocks, but can’t really answer what matter is. This is a consequence of the scientific method, through which hypothesis are falsified and theoretical predictions are verified. This process ensures that the lasting theory has endured and all the predictions based on it have been verified, this however doesn’t mean that some future prediction may fail meaning a new refinement of the theory is required. As a consequence what science can definitely say is how the real world is not. It can’t be anything that produces falsifiable results, since these results are a definite prove that the world is not how we propose. Thats why science will never be able to answer what anything is, only what it is not.

In this sense matter is not a continuous media, since it is made of discrete pieces (subatomic particles). Matter is not static since these particles are in continuous motion. Matter is definitely not mass since mass is only a measure of a body’s resistance to change of motion, inertia, which is a property of most matter (all except mass-less particles, like photons). Different type of matter interact with each other in different ways by four forces: gravitation, electromagnetism, weak force and strong force.


Today, in our scientific worldview most people have a materialistic perspective on nature and life. All matter is made of atoms and all that is or ever has been is made of the particles that constitute the standard model and possible some other particles not jet discovered. This begs the question of whether abstract concepts exist, and by “abstract concepts” here I include such things as chairs and tables, not only truly abstract ones as goodness and happiness. These concepts exist in our minds but not in nature, in a materialistic explanation these concepts don’t really exist they are generated from chemical reactions in our brains the same way awareness arises. And here is were the opposites touch, in a materialistic perspective abstract concepts don’t exist, because the are non-material, from the point of view of idealism or dualism they do exist but in a different “realm of ideas”. Both agree that these concepts are non-material and, in the sense that we use them every day, they undoubtedly must exist in some non-material way. The only difference is whether we disregard this non-material existence as non-existence. So in an ontological way the difference is really not that great as initially expected.



El hombre y la naturaleza

Estaba leyendo sobre el CO2 antropogénico en contraposición al de origen natural y casi sin darme cuenta empecé a divagar sobre la aparente paradoja entre estos calificativos sobre el origen.
Usamos el termino natural como el opuesto de antropogénico lo que inmediatamente califica de antinatural o artificial a la humanidad. Pero en el sentido mas estricto, no es el hombre parte de la naturaleza? En que momento se escindió la hombre de la naturaleza?
La existencia en el lenguaje de dos antónimos de la palabra natural: artificial y antinatural, que son dramáticamente distintos entre sí ponen de manifiesto la dicotomía del hombre en su relación con naturaleza.
El termino naturaleza viene del latín “natura” y significa de desarrollo espontaneo. En este sentido por un lado, resulta obvio que el hombre se desarrollo de forma espontanea en el mundo y es por tanto parte de la naturaleza. Sin embargo debido a su consciencia y razón, el hombre tiende a considerar su intervención como algo separado de la naturaleza, ya que se siente en capacidad de controlar o alterar su contribución. Este sentimiento esta en el corazón de la diferencia entre lo natural y lo artificial. De esta manera, la propia clasificación es artificial y puramente antrópica hasta el punto de ser antinatural. La naturaleza en sí no distingue entre una y otra parte del todo que conforman; siendo la clasificación contra natura ergo antinatural.
En la época moderna el hombre ha sido capaz a través de la ciencia de distanciarse de su posición antropocéntrica, un proceso complicado y lento que empezó con Copérnico y Galileo destruyendo la noción de la tierra como centro del universo, continuó con Darwin sacando al hombre de su posición privilegiada entre las especies y sigue en su proceso desbaratando hasta nuestros prejuicios metafísicos mas básicos: el espacio, el tiempo a través de las teorías Relativistas y cuánticas. El método científico nos ha permitido crear tecnologías inimaginables en tiempos anteriores.
Estas nuevas tecnologías nos capacitan para adaptar el mundo a nuestras necesidades y en el proceso repercuten en los procesos de la naturaleza. Esto nos hace conscientes de nuestra intervención pero no conocedores de su consecuencia ni capaces de controlar las implicaciones. Esto produce un cambio en la concepción de lo que caracteriza una acción de artificial: la culpabilidad, una emoción humana muy poderosa y como todas las emociones irracional. Este nuevo concepto lo calificamos de antropogénico: de origen humano, causado por el hombre. La introducción de esta palabra parece aclarar las cosas, pero en realidad solo complica la situación. Ahora tenemos, no dos sino tres antónimos, de una palabra paradójica desde su concepción, natural: antinatural, artificial y antropogénico.
La mente humana no trabaja bien con conceptos vagos y paradójicos por lo que inevitablemente se produce la siguiente relación cuando no encontramos con la palabra antropogénico:
CULPA–>antropogénico–>no natural–>artificial–>CONTROLABLE
Una falsa sensación de control, que unido a los avances tecnológicos y difusa frontera, para el hombre medio entre la realidad tecnológica y la ciencia ficción genera una ilusión de control. La ilusión de control y el fuerte sentimiento de culpa inevitablemente produce una necesidad irracional de reaccionar y mitigar las consecuencias de nuestra acción.
El uso de la misma palabra, natural para referirse a conceptos muy distintos: aquello que el hombre no se siente con capacidad de modificar o intervenir y aquello que no esta causado por el hombre, la convierte en un arma terrible a manos de políticos y figuras de los medios comunicativos que obliga al ciudadano medio a sentirse culpable si no favorece acciones de mitigación, que por otra parte están condenados a fallar por no estar el hombre en control de las consecuencias.
