Logic: a very short introduction

Validity : what follows from what?

Truth functions : or not?

Names and quantifiers : is nothing something?

Descriptions and existence : did the Greeks worship Zeus?

Self-reference : what is this chapter about?

Necessity and possibility : what will be must be?

Conditionals : what's in an if?

The future and the past : is time real?

Identity and change : is anything ever the same?

Vagueness : how do you stop sliding down a slippery slope?

Probability : the strange case of the missing reference class

Inverse probability : you can't be indifferent about it

Decision theory : great expectations

Halt! What goes there?

Maybe it is true

but you can't prove it!

A little history and some further reading.
