Focus on the utility of things
Define "glasses".
The purpose of expression is to convey ideas
The function can be turned into language, and the most fundamental intention can be expressed through language.
By changing the narrative, we can communicate our thoughts and thoughts directly to others, and we can also record them in written form.
Language is also the embodiment of a form and belongs to the world of forms. We're not going back to a world of exactly the same form as we were at the beginning, and that's what makes functional analysis unique.
When we define the function of things, we follow some kind of rule or law.
When we express our ideas, we should choose words that are simple in form and clear in meaning, and in this sense, function is a very simple and simple concept.
It's not the glasses themselves that are really wanted.
For example
In the sentence "glasses are an item for correcting vision", glasses are the subject and glasses are used to "correct vision". This way of defining "glasses" belongs to the expression in the world of forms.
Glasses is a name. In this sentence, "spectacles" and "eyesight-correcting objects" are interchangeable, and they are meant to explain the same object.
What people really want is not the glasses themselves, but the objects that can "correct their vision".
When thinking and discussing a problem, you should not just think about itexternal form and presentation mode, but should think deeply about its function, and repeatedly discuss how to achieve its function, which is the real reasonable dismantling thinking.
For the specific functions of the three items mentioned above, we should use the following language:
The purpose of designing the manhole cover in a circular shape:Eliminate directional differences;
The purpose of leaving a certain gap between the rings on the bus:Lateral movement is allowed;
The purpose of designing the outer ring of the plastic bottle cap into a zigzag shape:Increase friction.
