0 - 2. Through the previous post we discussed how a subject is created in our mind (the word "image" might be misleading since it refers to the visual aspects of things, so from now on we use the term "subject" instead.); and we saw the difference between a flower as object and subject. After identifying the existence of a single thing and creating its subject, we need to analyze it, so the first step to analyze something is comparison through which we conceive similarities and differences that help us to categorize subjects. Everything
is unique in the world, even these two laptops which are identical; because
each has occupied a unique space. Moreover, they have their own unique materials.
Our brain understands the similarities.
For some objects such as these two laptops, it is easy to do so,
but what can we say about these two horses?
We see that they are
different and the first important difference is their color. So what our mind
does to conceive the similarity is ignoring the difference in color and probably some negligible differences between other features, apart from
that they look alike.
What are the similarities between a
tree and a horse?
So you see that in order to find the similarities, our mind should
disintegrate the components of things to find the similar components which might not be visible. This
process is called abstraction.
Picasso has shown us the finest example of
abstraction. He might have aimed to see how much he could simplify the details of a bull
such that people could find the similarity between the drawing and a bull.
You will see that in mathematics, we
deal with abstract ideas. For example, if we’re asked to calculate the volume of
a bottle, we ignore its color, material, mass, price and other dimensions and we
just include the shape and size in our calculation. So to understand
mathematics, we should grasp the abstract ideas which are apart from the reality. It will be discussed later thoroughly.
