Generally speaking, the word Abstract refers to something not concrete, which lacks its own reality and therefore, in many cases even materiality. An idea or an art, for example, fits perfectly with this description, the idea cannot be touched or seen, it will only be accessible to human beings through the implementation of reason.
Preeminently, The abstract term enjoys a special participation in the art world as a consequence of abstract art, which is an artistic style that aims to highlight aspects such as color, shape and structure, accentuating them even more, in order to mark its strength and expressive value and that of course will stay away from all kinds of imitation of models or natural forms.
For those artists who promote this type of style, the important thing is not to represent the things of nature as they are presented before our eyes, because in addition it would be almost unlikely to be able to repeat them with great fidelity, what they are interested in is creating a autonomous visual language that speaks for itself, that is, that is endowed with its own meanings that are not related to questions or things that we can see or touch in reality.
As always happens when great changes take place, it will be the need to assume the latter, which occurred with strength and presence in the field of science, philosophy and technology, which laid the foundations towards the end of the 19th century for this type of art, which certainly faced the artistic order established up to that moment, in which the logic of perspective and attempts to reproduce the illusion of the reality that was seen predominated, laying the foundations of what was to come ... however , it would not be until the year 1910, in which it would emerge in a very pure state and as a reaction to realism and photography.
