Slide 2

Review For all P, P is a law of nature iff . The Regularity Theory : For all P, P is a law of nature iff P is an unexpectedly genuine speculation. Protest #1 : Restricted Generalizations Objection #2 : Vacuous Generalizations Objection #3 : Accidental Generalizations

Slide 3

Deductive Systems The Revised Regularity Theory : For all P, P is a law of nature iff P is an unexpectedly genuine speculation that . A deductive framework is a gathering of adages, together with principles of induction. A hypothesis is any announcement that takes after from the aphorisms by the guidelines of surmising.

Slide 4

Euclidean Geometry Any two focuses can be joined by a straight line. Any straight line section can be augmented uncertainly in a straight line. Given any straight line section, a circle can be drawn having the fragment as sweep and one endpoint as focus. Good edges are harmonious. Parallel propose.

Slide 5

Newtonian Mechanics First Law : A body very still stays very still, and a body in movement keeps on moving in a straight line with a steady speed unless and until an outside uneven constrain follows up on it. Second Law : The rate of progress of energy of a body is specifically corresponding to the awed drive and happens in the course in which the compel demonstrations. Third Law : Whenever An applies a drive on B, B is all the while applying a compel of a similar size on A, the other way.

Slide 6

Deductive Systems what number aphorisms are there? How convoluted would they say they are? How intriguing are the hypotheses? How appropriate would they say they are? The best deductive framework is the one that accomplishes the best adjust of straightforwardness and quality.

Slide 7

The Ramsey-Lewis Theory The Ramsey-Lewis Theory : For all P, P is a law of nature iff P is an unexpectedly genuine speculation that has a place with the best deductive framework. Complaint #1 : Restricted Generalizations All the items in this room apply a drive on each other conversely relative to the square of the separation between them.

Slide 8

The Ramsey-Lewis Theory The Ramsey-Lewis Theory : For all P, P is a law of nature iff P is an unexpectedly genuine speculation that has a place with the best deductive framework (as a saying or a hypothesis). Complaint #1 : Restricted Generalizations All the articles in this room apply a drive on each other conversely relative to the square of the separation between them.

Slide 9

The Ramsey-Lewis Theory The Ramsey-Lewis Theory : For all P, P is a law of nature iff P is an unexpectedly genuine speculation that has a place with the best deductive framework. Complaint #2 : Vacuous Generalizations All plaid panda weigh precisely five kilograms.

Slide 10

The Ramsey-Lewis Theory The Ramsey-Lewis Theory : For all P, P is a law of nature iff P is an unexpectedly genuine speculation that has a place with the best deductive framework. Complaint #3 : Accidental Generalizations All gold circles are not exactly a mile in width. All uranium circles are not exactly a mile in distance across.
