Michael Crafferty Posted almost 2 years ago Is science just imagination in a straitjacket? I do not think the quote by Feynman is meant to indicate restriction in quite the way you are taking it. For example, great writing is made within the "straitjacket" of haiku or iambic pentameter. Both are examples of a very rigid and restrictive formula, but an author can use the confined form to express the most expansive ideas. An artist can sometimes use restrictions as a foil instead of being foiled by them. Imagination within the straitjacket of science can work in a similar way. You can struggle against the sure bindings or you can learn to let your imagination be unfettered by them and go on to discover something beautiful.
