Traditional Advice
Considerations and the resulting theories should be free of contradictions, consistent and coherent, i.e. the individual steps of thought should build on each other logically and be comprehensible. To achieve this goal, thinkers from different eras have given good advice. And to come up with new ideas, you also need a dose of creativity. For this too, there are tried and proven methods.
"If I have an hour to solve a problem,
then I spend 55 minutes on the problem
and 5 minutes on the solution."Albert Einstein (1879 - 1955)

unless it is evident
or known on the basis of experience
or is secured by the authority of Holy Scripture.
Wilhelm von Ockham (1288 - 1347)
