Abraham Lincon's philosophy - [an ideology of geometry] -

That the source of purpose;
is a foundation of reason that is
the cause.

Example:

a. /\ = foundation

b. / \ = ?

'B' - is the foundation for - 'A'.
'A' - must combine the element(s-) of 'B'.
Because B is the foundation.
Therefore, A.

When you combine both foundation with '?'
together A - B,
represent a prism or diamond shape.
