I'm reading a book, and I came across the following quote by Horatius Bonar.
Think truly, and thy thoughts shall the world's famine feed.
Could anybody explain what it means?
Think truly, and your thoughts will feed the world's famine.
It probably does not refer to food. The famine is the dearth of truth. Seek truth, and you can mitigate the shortage.
It means that your thoughts will provide you with prosperity in order that you may feed others in the world that are less fortunate.
I apologize for putting it so crudely before
It means that true (or right or clear) thinking will solve all problems…
It's almost an extension of Newtonian physics: start from true measurements, apply true thought and the outcome will be true.
That the famine won't be solved can be attributed to poor measurement of the initial conditions.
