You don't.

And you thought that to fall into 'totally certain' category? <LOL>
Second, 'certainties', of a kind, can still exist without induction. What is experienced directly and in the moment - like the visual sensation of "red", for example. Or even when I use language to utter the word "red" in the moment.
1) These 'certainties' are grounded in the 'uncertainty' of your cognitive development at the very least. You are claiming that you can build a solid rock of certainty in the middle of an infinitely deep ocean of uncertainty.
2) The things you mentioned aren't nearly as certain as you think. In fact, it's amazing how uncertain our own introspection is. For a more detailed exposition of this, read Dennett's "Quining Qualia".

And your present self
is grounded in those past uncertainties. They infuse everything about you, so your presumption that you can extract certainty from uncertainty is, shall we say, bizarre.

Wrong answer.
Try again. :)
Free hint:
fallibilism, which is what I am advocating, is not the same thing as acontextual skepticism. There is a subtle but critically important difference between the two: acontextual skeptical positions, such as pyrrhonism, hold that knowledge is
impossible; fallibilism instead holds that knowledge is possible but
uncertain and provisional.
P.S. You should really read "Two Dogmas of Empiricism". Really. And "Quining Qualia" too.
