A Posteriori Quotes (2 quotes)

Behold the mighty dinosaur,

Famous in prehistoric lore,

Not only for his power and strength

But for his intellectual length.

You will observe by these remains

The creature had two sets of brains—

One in his head (the usual place),

The other at his spinal base.

Thus he could reason 'A priori'

As well as 'A posteriori'.

No problem bothered him a bit

He made both head and tail of it.

So wise was he, so wise and solemn,

Each thought filled just a spinal column.

If one brain found the pressure strong

It passed a few ideas along.

If something slipped his forward mind

'Twas rescued by the one behind.

And if in error he was caught

He had a saving afterthought.

As he thought twice before he spoke

He had no judgment to revoke.

Thus he could think without congestion

Upon both sides of every question.

Oh, gaze upon this model beast

Defunct ten million years at least.

Nor need you doubt that Pythagoras, a long time before he found the demonstration for the Hecatomb, had been certain that the square of the side subtending the right angle in a rectangular triangle was equal to the square of the other two sides; the certainty of the conclusion helped not a little in the search for a demonstration. But whatever was the method of Aristotle, and whether his arguing a priori preceded sense a posteriori, or the contrary, it is sufficient that the same Aristotle (as has often been said) put sensible experiences before all discourses. As to the arguments a priori, their force has already been examined.
