WHAT IS KNOWLEDGE

WHAT IS KNOWLEDGE

When we talk about knowledge what we mean is knowledge about some object. Informally, knowledge is a description of the state of some object. The object may be either physical or abstract. Some examples of abstract objects include love, hate, memory, the future, and even knowledge itself. We naively believe that our knowledge of reality is direct, but this is a mistake. Our experience with physical objects is actually indirect. We do not directly mentally experience physical objects; we mentally experience only our concepts of them.

Knowledge can be defined as a relation between two or more concepts, where concepts are mental objects. But these concepts do not exist apart from a conceptualizer, an intelligent being. Thus human knowledge is subjective and has no absolute meaning.

Knowledge is very much like sound and colour. When a tree falls in the forest it is assumed to make a lot of sound waves, but if there is no creature nearby capable of hearing, then it makes no sound. Likewise, when light reflects off an object it produces characteristic wavelengths of light, but neither the object nor the light are colored in themselves. Color exists in the mind of the perceiver. Color and sound are the brain’s method of making sense out of external signals picked-up by our sensory organs. Knowledge does not exist without a knower, and there is no such thing as “unknown” knowledge.

Human knowledge is a subjective means of coming to grips with the world. As far as we can prove, human knowledge never captures the essence of reality; it merely characterizes it according to our own purposes.

Knowledge certainly exists for it is an invention of man. It serves man by offering a metaphorical and subjective characterization of the “known” world. Human knowledge has no absolute status for it is founded on arbitrary definitions. If we change our definitions, we change the way we characterize the world, though presumably the world remains unchanged. That knowledge has no absolute foundation to man is the inevitable result of the pluralistic nature of the world. In a sense, though, knowledge can be said to be “true” when it is understood that knowledge represents the appearance of the world rather than the “real” world itself. Logic has its value as a limited means of gaining knowledge about the world.

In normal conversation we use knowledge to mean:

  • Knowing that (facts and information)
  • Knowing how (the ability to do something)

Sometimes, we use the word knowledge to mean that we have some information, we know that Mary drinks lemonade, for example. When we have this type of knowledge then we are able to express it. I cannot say that I know when the Battle of Hastings took place, if I cannot, under any circumstances, say the date! This is not true of knowing how.

If I know how to swim, then when placed in the water I make certain movements and do not sink! However, I may be unable to say how, exactly, I am able to swim. Knowing how does not mean I know that … If I cannot say the date of the Battle of Hastings, I cannot be said to know it. But if, while swimming, I cannot tell you exactly how I do it, you cannot say I don’t know how to swim!

Failing to understand the above can lead us into certain fallacies. If we get instruction from the best public speaker  in the world, it does not mean that because he or she can speak excellently, that they know how to instruct others. They might be able to say what they do. For example they might say how they practice. But this might work for

Estimate the Number of Pet-owning Households

To estimate the number of pet-owning households in your community, multiply the total number of households in your community by the percentage of households that owned pets. For dogs and cats you may replace the national percentage with the percentage for the state in which the community is located. For birds and horses you may replace the national percentage with the percentage for the region in which the community is located.

The demographics of the state or region may be more similar to the demographics of your community, but, as indicated above the state and regional estimates have a greater degree of statistical error associated with them than the national estimates. Therefore, without additional analysis, it is undetermined whether an estimate for the number of pet-owing households in your community will be more accurate by using the national estimates, regional estimates or state estimates.

Formulas for estimating the number of pet-owning households using national percentages:
All Pets: Number of pet-owning households = .56 x total number of households
Dogs: Number of dog-owning households = .365 x total number of households
Cats: Number of cat-owning households = .304 x total number of households
Birds: Number of bird-owning households = .031 x total number of households
Horses: Number of horse-owning households = .015 x total number of households

Formulas for estimating percentage of pet-owning households and pet population in your community

Most communities do not have data on the number of households that own dogs, cats, birds, or horses, nor do they have data on the numbers of these pets in their communities. The following formulas can be used to estimate the number of pet-owning households and pet populations in your community.

These formulas will give you an approximation of the number of pet-owning households and pet populations. These formulas assume that the demographics and rates of pet ownership in your community are similar to national, state and regional demographics and rates of pet ownership. However, because these formulas use sample survey data, they should not be considered 100% accurate.

To use the formulas below you need to know the total number of households in the community in which you are estimating. If you only know the population of the community, you can estimate the number of households by dividing the population of the community by the average number of members per household. In 2011, the U.S. Census Bureau’s Current Population Survey estimated that there were 2.6 members per household.
