Everything is merely a smaller part of a greater thing; that is, it is an attribute or property of something else. In computer programming this is called Object-base. An object has properties that can be set or changed. For example, the screen on which you are reading this has properties such as width, height, contrast, tint, brightness pixel ratio among many other attributes. Some of these attributes are only readable and cannot be changed or written. In a more complex example, think of a human being. Some of our properties or attributes are: gender, age, race, height, eye color. With DNA mapping, some of these properties may move from being only readable to writeable properties. Everything is a thing of some other thing of some other thing and on and on.
If everything is merely a property of something else, then we wonder if there is an original or first thing from which all other things come. After all, according to science, almost everything is the SAME when broken down into atoms...at least that's what we used to think. (ref - advance to Session 4; Are All Atoms the Same?) If we could manipulate things on a subatomic level could we re-create a larger more complex thing? Isn't this the stuff of science-fiction such as replicators and transporters that materialize things from atoms? So, is the first thing really that smallest unit or property; even smaller than an atom? These properties are called particles.
In the field of particle physics, the hunt for the God particle; the first thing has assumed to be revealed. Does this mean this is the beginning of all things? Does this mean this first thing is god in the scientific sense? Since even the God particle is somewhat theoretical in that the field in which it supposedly exists; the Higgs Field is imaginary, then it's possible we have not really found the smallest property; the thing from which all things are made.
The variation of properties a thing can have is limitless. When we spoke of human properties we only outlined a few but as you know, classifying just the properties of a human would fill volumes; hair color, hair length, hair coarseness, hair density, hair strength and on and on for example. Thus, when we look at a thing, we must start at the macro or top level and then assess the smaller or micro levels of the thing. Getting caught up immediately on micro aspects of a thing bogs us down even though we are told a thing is merely a sum of its parts. The arrangement of the parts is also important. All the parts may be the same, much as the pixels on a screen are merely little circles or squares of colors arranged in a way to display a larger image. As you look around you, notice all the things and their parts; their properties. Notice other things in comparison and their shared properties.
As a VBA programmer (VBA is used in Microsoft Applications such as Excel and Word), I deal with objects every day. A workbook has properties such as sheets or tabs and these sheets have properties such as columns, rows, ranges, cells. These cells have properties such as format, font style, color, size, fill, interior, exterior and on and on. I can change some of these properties either via the basic interface of Excel or by using VBA programming to effect the change. However some of the properties are only viewable or readable. I can access and display the properties but I cannot modify them. In this object-oriented programming I organize things as things of other things; sort of like you would a bullet-pointed list. Interestingly enough, the world is also object-oriented. Everything is a thing of a thing. Where we are being told not to classify, not to categorize and not to label things; the REALITY is that everything is a category or class of something else. Humans are classified as primates, as biped primates, as mammals, as animals and on and on. To ignore that the world is object-oriented is to ignore reality. However, it is always possible that we erroneously classify things. If this is done within VBA programming, an error will occur. A popup will result telling you something like the property you are trying to change doesn't exist or doesn't exist as a child of the thing of the thing of the thing you think it is a part or that it simply is not writeable.
While we can change; or re-write various properties of ourselves as some properties can be masked to appear different but at the core cannot really be changed. For example, a person may change various properties to give the mask or appearance of a gender change, but at the DNA level, they are still either male or female; the two options for the read-only property called gender. In programming it may look like this:
See how everything is a thing of a thing? See how computer programming is merely the orienting of objects and their properties to function in one way or another? Programming is less mathematical and more "diagram-ical", such as the way you might diagram the parts of a sentence as verbs, nouns, subjects, and adjectives. Once you understand this, programming isn't as difficult to decipher. Look for the objects or things within a program code and see if you can see how the object is being acted upon or accessed for its properties. Seeing everything in this micro vs macro, atomic manner has given me a new perspective and a new appreciation for the concept of a thing is the sum of its parts.
