I Kinda Disagree

I read 1984 over the summer actually, its a good book (only two hundred and sumthing pages). It proposes the idea of how trying to attain a utopia creates a dysfunctional dystopia. I found the idea very thought provoking and its entertaining because it's so unbelievable. There's these law enforcement in the book called thought police (interesting eh?) It's main message is similar to that of Lois Lowry's The Giver.
But I don't think a philosopher can be a leader because philosophy is basically about searching for all possible avenues without declaring one to be coorect or even choosing one. It's a concept of uncertainty, and a vital charachteristic of any leader is decisiveness.
