Document Summary
B must have a helper; either a or c must help. If a helps, he"s guilty, if c helps, then he must use a as well. Some truths (a priori) can be known by use of concepts/reason and without any particular experience/observation (a posteriori: ex. All bachelors are unmarried, 1725 x 235 = 405 375, the sum of the angles of a (euclidean) triangle is 180 , if fred weighs more than nancy, then nancy weighs less than fred, red is a color, etc. A priori truths and existence: some a priori truths entail existence. There is a prime number between 50 and 55. Concrete entities: real tangible objects: how do a priori existence claims affect the question: why is there something rather than nothing, an a priori existence claim might answer that question. Two distinctions: a priori/ a posteriori, necessary/contingent. The ontological argument recall ontology: metaphysics concerned with the nature of being.
