The Roots of Violence:
Wealth without work,
Pleasure without conscience,
Knowledge without character,
Commerce without morality,
Science without humanity,
Worship without sacrifice,
Politics without principles.
 
Mohandas K. Gandhi
 
 
Science is built up of facts, as a house is built of stones;
but an accumulation of facts is no more a science than a heap of stones is a house.

Henri Poincaré
