Anyone know how development can be linked in to this statement, and also any points both for and against this statement are welcome
Not true. Lennie is absolutely intrinsic to the core of what Of Mice and Men is about.
- He establishes the essential needs of men
- He proves the importance of the theme of Steinbeck's, the fraternity of men.
- He is the keeper of the dream; once he dies, so, too, does this unrealistic dream. Only the childlike Lennie has been convinced of it, but his optimism encourages the other men to believe and have hope in their lives.
- He is essential because, as Steinbeck himself explains, Lennie "...was not to represent insanity at all but the inarticulate and powerful yearning of all men."
I agree with the previous post. Clearly, Lennie offers something to George. It is partly companionship. It is also, perhaps, the chance to be needed. Finally, Lennie offers people the chance to be with someone who really is pure at heart and not selfish or greedy or anything else like that.
To make a statement against the statement, we might say that Lennie offers companionship. We see this in his relationship with George. Crooks also comments on this idea when he speaks with Lennie in his room in the stable.
