They can, and are, also used in synergy with clearly stated logical axioms; to accomplish the same goals. Any presidential speech is an example of this. I'm familiar with Stephen Kellert's work regarding attitudes about wildlife, which is a perfect example.
Attitudes are divided into 9 categories, each clearly influenced by different combinations of different ways of knowing (e.g. humanistic folks who dress their lap dogs in custom doggie clothing as if they were children are more influenced by emotion than utilitarians):
Naturalistic is the primary interest and affection for wildlife and the outdoors.
Ecologistic is the primary concern for the environment as a system, for interrelationships between wildlife species and natural habitat.
Humanistic is the primary concern and strong affection for individual animals, principally pets.
Moralistic is the primary concern for the right and wrong treatment of animals, with strong opposition to exploitation or cruelty towards animals.
Scientistic is primary interest in the physical attributes and biological functioning of animals.
Aesthetic is primary concern in the artistic and symbolic characteristics of animals.
Utilitarian is primary concern for the practical and material value of animals of the animal's habitat.
Dominionistic is primary interest in the mastery and control of animals typically in sporting situations.
Negativistic is primary orientation for an active avoidance of animals due to indifference, dislike or fear.
But wildlife is a public resource in the U.S., designated through the constitution itself (In England, all wildlife belonged to the king. The "King's Deer", etc. The founding fathers didn't like that very much

). Because of this, all of these attitudes must be compiled into a comprehensive management plan, the goal of which is to appease everyone as much as possible. To quote Teddy Roosevelt "The purpose of conservation: the greatest good to the greatest number of people for the longest time."
