When a child begins to play games... he enters the gateway to reason and imagination together. - Jacob Bronowski

The act of imagination is the opening of the system so that it shows new connections. Every act of act of imagination is the discovery of likenesses between two things which were thought unlike. An example is Newton’s thinking of the likeness between the thrown apple and moon sailing majestically in the sky. Hence, the ‘discovery’ of the laws of gravity.

There has never been a great book or a powerful work of art which has not been thought immoral by those with an older tradition.

[T]he human reason discovers new relations between things not by deduction, but by that unpredictable blend of speculation and insight... induction, which—like other forms of imagination—cannot be formalized.
