"Our idea of space boundless."

"This, I think is the way whether the mind gets the idea of infinite space. It is a quite different consideration to examine whether the mind has the idea of such a boundless space actually existing, since our ideas are of the existence of things; but yet, since this comes here in our way, I Suppose I may say that we are apt to think that space or expansion of itself naturally leads us."
I agree with this I have a boundless space that I keep. I don't like when people get to close to me. For example when some one is talking to me I like them to be about 8ins way or more. I don't like when people get in my face and I can feel them breathing when the talk or smell their breath. Back up! I think that this is just respect for the person you are talking to and yourself.
I know that is an individual thing that makes me feel this way and that in some cultures it is normal to be right in someone face and to be close and touch. That's not my style I want some one to keep their distance form me and not to touch me.

Locke is right this is a mind set of an individual and it is up to the person how they feel about bounties with other people. However I think that all people show respect the boundaries of other and keep a distance form people when they talk.
