Bri,
Your questions are very profound. You ask:
1. Is it wrong for Man
to think himself special?
2. Is a Man more precious
than an animal or plant?
A quick answer to number 1 would be, in my opinion, that it is self-evident that man is very special and far superior to all other beings below his rank (mineral, vegetable, animal).
My quick answer to number 2 is the same; man is, indeed, much more precious than the animal and plant.
I note that some of the posters here have opted for a negative view, concentrating only on those aspects of human existence which are secondary to the true worth of "man".
The true worth of any person on this wonderful planet is determined by the breadth of his "learning" and by the degree to which he has accepted to humble himself before the realization of his utter ignorance which true learning brings about. For, you see, with learning must come either arrogance or the eventual and inevitable realization that he is ignorant (and this is a very special type of realization, mind you).
The knowledge a person acquires is limited, circumscribed, relative, and is never infinite nor absolute; the knowledge we possess today is proven false by subsequent generations. Thus, an individual who prides himself in his knowledge, who adheres to it and waves his head in haughtiness and arrogance is truly below the animal level for it is such arrogance that causes harm, not the knowledge itself!
The pride of man rests in his humility. Although in many respects we are far superior to the mineral, vegetable and animal kingdoms (because we have awareness, intelligence, and a sort of 6th sense whereby we can synthesize items derived from our intellectual processes), yet humility would provide the awareness that, despite our superior station, yet we are dependant on the lower ranks for our very lives. Thus, our physical lives depend on the food that grows from the ground. Without it we would perish. Would it be right for us to despise a wheat field by claiming we are superior and the wheat inferior, worthless, something to be scorned? Nay!!! Our daily bread depends on that golden wheat field. It is necessary to see that everyone of the four ranks have special purposes but that out of all these four ranks man stands supreme in that he has an understanding which the rock, the wheat, the eagle are deprived.
The kingdoms of the mineral, vegetable, animal and human are all very special. Each and all are interdependent and need each other. Man is special only in that he has the faculty of reason and can understand something of creation and of his Creator which the lower ranks cannot.
If man thinks himself special in a harmful sort of way, downsizing others for example by bringing himself up to the level of superlative arrogance and self conceit, he is only proving, by such thought and conduct as are detrimental to others, that he is lower than the animal, for true knowledge, true understanding, leads a wise man to humility.
There is nothing wrong in realizing that we are intelligent creatures and superior to all other ranks below us. But humility is needed to understand that in truth all things are interlinked and dependent on each other.
An awareness of the unity of all things frees us from ourselves!
