All things 'interact' with all other things one way or another.
Their existence takes 'form' in conjunction with and by 'interacting' with others.
Form and interaction are logically congruent in the same way as one and nothing.
In a later section, this fact will be used to explain, at a rudementary level, the P and CP violations of the weak interaction.Therefore, we may assert without fear of error that:
That which has form but does not interact does not exist.
And, that which interacts but has no form is equally not possible.
(Plan on a slight modification later. All absolute statements collapse at some point of inquiry, even this one... and this one... and this one... and this one.................. )
