All relations are either qualitative or quantitative. Qualitative relations can be considered by themselves without regard to quantity. The algebra of such enquiries may be called logical algebra, of which a fine example is given by Boole. Quantitative relations may also be considered by themselves without regard to quality. They belong to arithmetic, and the corresponding algebra is the common or arithmetical algebra. In all other algebras both relations must be combined, and the algebra must conform to the character of the relations.

Of the various executive abilities, no one excited more anxious concern than that of placing the interests of our fellow-citizens in the hands of honest men, with understanding sufficient for their stations. No duty is at the same time more difficult to fulfil. The knowledge of character possessed by a single individual is of necessity limited. To seek out the best through the whole Union, we must resort to the information which from the best of men, acting disinterestedly and with the purest motives, is sometimes incorrect.
Thomas Jefferson
If... God highly exalted Christ because He humbled Himself, suffered dishonour, was tempted and endured a shameful cross and death for our sake, how will He save, glorify and raise us up if we neither choose humility, nor show love to our fellows, nor gain our souls by enduring temptation (cf. Lk. 21:19), nor follow the saving Guide through the 'strait gate' and along the 'narrow way' leading to eternal life (Mt. 7:14)? To this end we were called, says Peter, the chief Apostle, ' Because Christ also suffered for us, leaving us an example that we should follow His steps' (I Pet. 2:21).
Gregory Palamas
O God, enlarge within us the sense of fellowship with all living things, even our brothers, the animals, to whom Thou gavest the earth as their home in common with us. We must remember with shame that in the past we have exercised the high dominion of man with ruthless cruelty so that the voice of the earth, which should have gone up to thee in song, has been a groan of pain. May we realize that they live, not for us alone, but for themselves and for Thee and that they love the sweetness of life.
Basil of Caesarea
As is used in connection with systems engineering, a model is a qualitative or quantitative representation of a process or endeavor that shows the effects of those factors which are significant for the purposes being considered. Modeling is the process of making a model. Although the model may not represent the actual phenomenon in all respects, it does describe the essential inputs, outputs, and internal characteristics, as well as provide an indication of environmental conditions similar to those of actual equipment.

A model is a qualitative or quantitative representation of a process or endeavor that shows the effects of those factors which are significant for the purposes being considered. A model may be pictorial, descriptive, qualitative, or generally approximate in nature; or it may be mathematical and quantitative in nature and reasonably precise. It is important that effective means for modeling be understood such as analog, stochastic, procedural, scheduling, flow chart, schematic, and block diagrams.
