CA Identify the Premises and Conclusions Questions – Description
A. For the following arguments, determine what statement is the conclusion and what statement/s are the premises. You may state it or underline it or highlight it. Don’t forget to look for indicator words as they will signal a conclusion or the premises. The next exercise after, find the missing statement based on identification of the form.
1. God is that than which none greater can be conceived. If God were just an idea we could easily conceive of something greater, namely, a God who actually existed. Therefore, if God is that than which none greater can be conceive, then God must exist. (St. Anselm)
2. Titanium combines readily with oxygen, nitrogen, and hydrogen, all of which have an adverse effect on its mechanical properties. As a result, titanium must be processed in their absence. (World of Science Encyclopedia)
3. Artists and poets look at the world and seek relationships and order. But they translate their ideas to canvas, or to marble, or into poetic images. Scientists try to find relationships between different objects and events. To express the order they find, they create hypotheses and theories. Thus, the great scientific theories are easily compared to great art and great literature. (Giancoli, The Ideas of Physics, 3rd Ed.)
4. The fact that there was never a land bridge between Australia and mainland Asia is evidenced by the fact that the animal species in the two areas are very different. Asian placental mammals and Australian marsupial mammals have not been in contact in the last several million years. (Price and Feinman, Images of the Past)
