The phase shift idea can be understood and explained intuitively by means of the water analogy. Imagine you fill (sinusoidally) a vessel with water and you picture graphically this process (choose the half of the maximum water height as a zero level - the ground). Analogy. So, you first open and then close (sinusoidally) the supply faucet.

This circuit is an RC phase shift oscillator. I understand that we need 3 capacitors to get a 180° phase shift in the feedback circuit (3×60°, but the exact phase shift depends on the capacitor and resistor values, right?). From here.
