Plato

For the greater good.

Karl Marx

It was a historical inevitability.

Machiavelli

So that its subjects will view it with admiration, as a chicken which has the daring and courage to boldly cross the road, but also with fear, for whom among them has the strength to contend with such a paragon of avian virtue? In such a manner is the princely chicken’s dominion maintained.

Hippocrates

Because of an excess of light pink gooey stuff in its pancreas.

Jacques Derrida

Any number of contending discourses may be discovered within the act of the chicken crossing the road, and each interpretation is equally valid as the authorial intent can never be discerned, because structuralism
is DEAD, DAMMIT, DEAD!

Give me ten minutes with the chicken and I’ll find out.

B.F. Skinner

Because the external influences which had pervaded its sensorium from birth had caused it to develop in such a fashion that it would tend to cross roads, even while believing these actions to be of its own free will.

Confluence of events in the cultural gestalt necessitated that individual chickens cross roads at this historical juncture, and therefore synchronicitously brought such occurrences into being.

The possibility of “crossing” was encoded into the objects “chicken” and “road”, and circumstances came into being which caused the actualization of this potential occurrence.

Aristotle

To actualize its potential.

Buddha

If you ask this question, you deny your own chicken – nature.

It may very well have been one of the most astonishing events to grace the annals of history. An historic, unprecedented avian biped with the temerity to attempt such an herculean achievement formerly relegated to homo sapien pedestrians is truly a remarkable occurence.

Darwin

It was the logical next step after coming down from the trees.

Epicurus

For fun.

It didn’t cross the road; it transcended it.

Johann von Goethe

The eternal hen-principle made it do it.

We are not sure which side of the road the chicken was on, but it was moving very fast.

David Hume

Out of custom and habit.

Pyrrho the Skeptic

What road?

Philosophy will clip a chicken’s wings.
