Reflection Of A Shadow

I caught the reflection of my shadow on my truck and I wondered about the relationship between reflection and shadow; and came across this:

A shadow is the absence of light, a reflection is just that, the reflection of light. So a shadow comes from blocking a light source, a reflection comes from the bouncing of light of one source and on to another.

This sounds somewhat post-ecliptical.

I just found Seventy great photographic quotes:
