Philosopher Clerihews 

Karl Popper
Gave himself a whopper
Of a philosophical vocation,
Which was the repudiate the classical observationalist/inductivist form of scientific method in favour of empirical  falsification. 

René Descartes
Blew apart
Assumptions about the nature of reality
With Cartesian duality.

Baruch Spinoza
Sought to expose a
Widespread potential delusion
By claiming free will is an illusion.

Makes mediocrities
Of other ages’
