There’s a Sphinx in the front yard…

“Which creature has one voice
and yet becomes four-footed
and two-footed
and three-footed?”
“Man—who crawls on all fours as a baby,
then walks on two feet as an adult,
and then uses a walking stick in old age”.

“There are two sisters:
one gives birth to the other
and she, in turn, gives birth to the first.
Who are the two sisters?”

“day and night”
