On purpose

[Mark Knowles]

I am sure what applies to Newton applies to earlier and later scientists. 

I can't believe what I'm reading. Newton drove the scientific revolution! A basic understanding of historical periods is required before engaging in these kinds of discussions.

I think we have a very different perspective on human interests and motivations. I think these are much less variable from historical period to historical period. As we know that biologically humans are very much as they were 600 years ago, I don't think that they were so different in other respects.
