A lui? Pour lui? A eux? Pour eux?

[Katerina James]

For them, the history of communist thought has been remarkably simple; it has been the history of four hero thinkers.

 

French translation (Please explain mistakes, sil vou plait)

 

A eux, l'histoire de la pensi communiste a extremement simple; il a l'histoire des quatre penseurs.

 

Merci!

[Erwan]

Pour eux, l'histoire de la pensée communiste a été extrêmement simple; c'était l'histoire de quatre Grands penseurs.

 

I don't see how to translate hero (penseurs éroïques is may be a bit strong) here so I use "Grands" (Great)
