what is meant by a prima facie obligation
Prima facie The phrase is also used in academic philosophy. Among its most notable uses is in the theory of ethics first proposed by W. D. Ross, often called the Ethic of Prima Facie Duties, as well as in epistemology, as used, for example, by Robert Audi. It is generally used in reference to an obligation. "I have a prima facie obligation to keep my promise and meet my friend" means that I am under an obligation, but this may yield to a more pressing duty. A more modern usage prefers the title pro tanto obligation: an obligation that may be later overruled by another more pressing one; it exists only pro tempore.
Maslow's hierarchy of needs The most fundamental and basic four layers of the pyramid contain what Maslow called "deficiency needs" or "d-needs": esteem, friendship and love, security, and physical needs. If these "deficiency needs" are not met – with the exception of the most fundamental (physiological) need – there may not be a physical indication, but the individual will feel anxious and tense. Maslow's theory suggests that the most basic level of needs must be met before the individual will strongly desire (or focus motivation upon) the secondary or higher level needs. Maslow also coined the term "metamotivation" to describe the motivation of people who go beyond the scope of the basic needs and strive for constant betterment.[8]
