Everything is related to something else
The phenomenality of our life consists in our limitation to the conditions of space, time, and causation. We think of everything in terms length, breadth, and height. This is the quantitative assessment of the things of the world.
Everything is a quantity – it has some substance, and it is measurable in terms of length, breadth, and height. This is one of the conditions to which our mind is subject. You cannot think of anything without attributing to it a quantity, some shape, which is a characteristic of our involvement in spatial characteristics. The mental involvement in space, whatever it be, compels us to think in terms of quantity – length, breadth, and height. This is the specialty of space.
We also attribute a quality to an object. It is not that a particular thing is only constituted of length, breadth, and height. It has some quality, a characteristic that determines its essentiality, individuality, and distinguishes it from other things. If a particular object has no specific quality of its own, it cannot be distinguished from other objects. So, the multiplicity of things we perceive in the world is due to the characterisation of things in terms of the qualitative measurement.
One thing is quantity, another thing is quality, and the third thing is relation. Everything is related to something else. We connect one thing with another, we compare one thing with another, contrast one thing with another. This process takes place automatically in our mind, without much of an effort.
Every object has a mode or a condition of existence; it is in some situation, some context, some predicament. This is a philosophical finding, a way of analysis of experience, by which we note that quantity, quality, relation, and mode are inseparable from the object, whatever be that object. This conditioning of the mind is the phenomenality thereof.
