@JLNobody,
yeah...think of functions as ordered dynamics at work, the rotation of a key in a lock, the pumping of the heart, the opening of a door...but also in less linear terms on a 2 level of order, the very objects themselves as phenomena may well be dessicated further down as functions...for instance is the "yellowish" in the yellow a function in between a certain wave-length and the receptive apparatus in the subject ? ...and its not just about a relational interpretation between subjects and things...how does that wave-length works with other stuff ? a rock does not see yellow but might feel the pressure of a few quarks occasionally colliding with it here and there with a certain rhythm or frequency...conjugated functions give rise to new systems to new forms new objects, and further up in the chain, on another layer level these emerging objects will again form more function sets and more complex systems...functions may be more or less energy effective as they fulfil their role better or worse, think of them as a path in a labyrinth...the shortest way between 2 points input/output is always the more energy efficient...it has the best algorithm, the best set of instructions...equally "objects" may operate other, less optimal, functions...you can drink water with a spoon but a glass would do it better...in there is implied the specificity with you, the relation...functions necessitate further extrinsic order to be optimized...a hole in a spoon diminishes the optimal function when you are eating a soup...and so on and so on, you get the idea from there...
... the interesting thing with functions is that you don´t need any more to speak on "subjects" and "objects", they are the same at base level, they only differ in the type of the system they form...instead you speak only of sets...that is, systems of functions, which are things, interacting between themselves with yet more functions, to form new bigger sets, new "effects", new property´s...new things once more ! Nevertheless there is the need for one true substance at the bottom of the pyramid...I prefer the bit of information due to its abstract non material definition...but in ancient Greece they thought of atoms...it does n´t really matter much what one wants to call them, they are equal and the base of unity, of no transcendence in the world...
