"In digital circuit theory, combinational logic 
(sometimes also referred to as time-independent logic)
is a type of digital logic which is implemented by
Boolean circuits, where the output is a pure function of
the present input only."

Wikipedia, quoted in this morning's previous post as
commentary on Nabokov's phrase "combinational delight"

"Time past and time future
Allow but a little consciousness.
To be conscious is not to be in time
But only in time can the moment in the rose-garden,
The moment in the arbour where the rain beat,
The moment in the draughty church at smokefall
Be remembered; involved with past and future.
Only through time time is conquered."

— T. S. Eliot in Four Quartets

"I confess I do not believe in time." 

— Vladimir Nabokov in Speak, Memory

Speak, Memory

Continued from Halloween 2012.

Suggested by yesterday afternoon's Combinational Delight.

"…the output is a pure function of the present input only.
This is in contrast to sequential logic, in which the output
depends not only on the present input but also on the
history of the input. In other words, sequential logic has 
memory  while combinational logic does not."
