On Solving the Dreaded Problem of Induction

On pages 70-71 in my new book, The Outsider Test for Faith: How to Know Which Religion Is True, I basically solve the problem of induction. Well, I point the way anyway. What is this problem?

In inductive reasoning, scientists make a series of observations and then infer something based on these observations, or they predict that the next observation under the same exact test conditions will produce the same results. It’s argued there are two problems with this process. The first problem is that regardless of the number of observations it is never certain the next observation of the same exact phenomena under the same exact test conditions will produce the same exact results. For scientists to inductively infer something from previous results or predict what future observations will be like, it’s claimed they must have faith that nature operates by a uniform set of laws. Why? Because they cannot know nature is lawful from their observations alone. The second problem is that the observations of scientists in and of themselves cannot establish with certainty the validity of inductive reasoning.

There is a great deal of literature on the problem of induction, and I cannot solve it here…But if all we ever do is think exclusively in terms of the probabilities, as I’ll argue later (in chapters 7 and 10), then this problem is pretty much solved.

I write more about it, but can you catch my drift?

    There’s also Nelson Goodman’s “new riddle of induction”, concerning the question of which among all logically possible predicates and/or sets of referents are deemed relevant for inductive projection. This is the famous “grue”/”bleen”/”blue”/”green” problem.

    Basically, every set of inductive data points can be characterized in an infinity of ways. For example, all the observations for the proposition that “tigers are carnivorous” are also observations for the proposition that “gorbles are fluzzivous”, where a gorble is either a rabbit belonging to a female U.S. President or a tiger not belonging to a female U.S. President, and something is fluzzivous iff it is carnivorous while on Earth and eats only marshmallows while in outer space.

    “Gorbles are fluzzivous” is obviously a bad conclusion despite having a huge number of supporting observations and zero exceptions. The upshot is that in addition to a general belief that lawlike regularities will continue, we also need some kind of trust in the kinds of categorizations that strike our brains as good, non-capricious ones.

    i don’t want to deal with all these little atheist f*ckers anymore….

    Atheism will NO LONGER EXIST after we finish…

    We have seen the problem of induction in action in physics. Observations of particle-antiparticle annihilations were consistent in producing identical results until the number of observations became very large. It turned out that there was a very slight imbalance in the reactions that caused more matter than antimatter to be produced. For example: for every 10,000,000,000 anti-protons, there will be 10,000,000,006 protons.

    I doubt this has much effect outside the realm of subatomic particles.
