I'm curious about the passive voice forms (if any) of the sentences,

I am


I think, therefore I am.

  • I am defeated looks pretty "passive" to me. What definition of "passive" are you thinking of? Jul 6 '21 at 13:57
  • No passive forms in your sentences according to the generally accepted understanding of the word passive in grammar.

  • ACTIVE A friend gave him a book PASSIVE A book was given to him OR He was given a book [by his friend] You need a transitive verb to construct a passive construction.

Only transitive verbs can be made passive in English.

Think can be transitive, but here it is not, so has no passive.

The copula am has no passive.


Thoughts were processed by him, therefor he exists.

This is, I believe, as close as one can come to a passive form of

I think therefore I am.

which is famously an English translation of the Latin

Cogito ergo sum

and has been influenced by Latin Grammar.

The above passive form is a much weaker statement.

There simply is no passive form of "I am".


I, an idea, am thought... (Very weird, but can be constructed.)

...therefore, uh, I am. (No passive voice construction here.)

  • It is not very clear what you are saying. You could edit to explain.
