induction is circular because of the following: A turkey is fed every single day of his life by a human, doing nothing but eating. Tomorrow is Christmas, since every previous day of the life of the turkey ended up with him being fed, he is going to get food and survive christmas.
However, the turkey dies, because the human was only making him fat to eat later.
Is the sun going to rise tomorrow? "Yes, because it has always risen every single day" But on what ground does the fact that the past remains the same implies the future will be the same? "Because it has always worked".
