The essay 'The World Within, The World Without - Sunday Talks With My Children’ by the Scottish sociologist and pioneering town planner Sir Patrick Geddes, takes the form of a conversation with his children about the difference between ‘Work, play and lessons'.

Geddes speaks about the difference between ‘thinking' and ‘doing'. He then goes on to illustrate the idea of there being two types of travellers - "those who sail round the world, or climb higher and higher upon its mountain peaks” and the other type of traveller that goes further “in their chairs and in their dreams”.

The essay touches on ideas of ‘Facts, Memories, Plans, Acts, Mystics, Pilgrims’ and his ideas about the inner world and the outer world.

It's a beautiful positive book essentially saying that we make change from within, and that both dreamers and doers are needed in the pursuit of any endeavour.
