Passive Voice Alterations?
I am currently working on a scholarly piece that has a history element. I am attempting to change as many sentences with a passive voice to active voice as I can. I have included a few examples of sentences I am struggling with: >Pythagoras is said to have encouraged his followers to ‘‘... >The Neopythagoreans claimed Pythagoras’ ideas, none of which were documented, were later plagiarized by Plato, Aristotle and other Late Greek philosophers (... I feel like I could figure out how to reword but as for sentences like the first, I do not know exactly who says and it feels wrong to just say "experts" or "writers." I also really enjoy the way the second sentence is written but it is written entirely with a passive voice. Does anyone have any input on how to change these sentences and similar sentences?
