An abstraction is an idea, concept, or word which defines the phenomena which make up the concrete events or things which the abstraction refers to, the referents. Abstractions are sometimes used that have ambiguous referents, for example, "happiness" used as an abstraction, can refer to as many things are there are people and events or states of being which make them happy.
A further example, suppose one attempts to define the term architecture and what it refers to: architecture is more than simply designing safe functional buildings; it involves also an element of creation which aims at elegant solutions to problems of construction and use of space. At its best, it evokes an emotional response in the builders, owners, viewers and users of the building
In philosophical terminology abstraction is the thought process wherein ideas are distanced from objects.
Abstraction uses a strategy of simplification of detail, wherein formerly concrete details are left ambiguous, vague, or undefined; thus speaking of things in the abstract demands that the listener have an intuitive or common experience with the speaker, if the speaker expects to be understood.*
For example, lots of different things have the property of redness: lots of things are red. And we find the relation sitting-on everywhere: many things sit on other things. The property of redness and the relation sitting-on are therefore abstract.
Problems begin to arise; however, when we try to define specific rules by which we can determine which things are abstract, and which concrete.
Lots more here *The underlined part explains how I tend to think and speak. I like making connections and then not bothering to explain them to anybody who may be listening. If you can't read my mind, 'good luck' is all I need to say.
Plus, I'm lazy, and don't like to have to study all the details. Simplicity is nice, ignorance is bliss. I'm somewhere inbetween, and can't stand it.
Though I know I'm the only one who can change my situation, I think I'd rather wait for some Prince Charming to come along and help me out. I don't care much for being alone.
Where beauty is, then there is ugliness;
where right is, also there is wrong.
Knowledge and ignorance are interdependent;
delusion and enlightenment condition each other.
Since olden times it has been so.
How could it be otherwise now?
Wanting to get rid of one and grab the other
is merely realizing a scene of stupidity.
Even if you speak of the wonder of it all,
how do you deal with each thing changing?
