Metaphor in Context
Once I had established these maxims and set them on one side together with the truths of faith, which have always been foremost among my beliefs, I judged that I could freely undertake to rid myself of all the rest of my opinions. As I expected to be able to achieve this more readily by talking with other men than by staying shut up in the stove-heated room where I had had all these thoughts, I set out on my travels again before the end of winter. Throughout the following nine years I did nothing but roam about in the world, trying to be a spectator rather than an actor in all the comedies that are played out there. Reflecting especially upon the points in every subject which might make it suspect and give occasion for us to make mistakes, I kept uprooting from my mind any errors that might previously have slipped into it. In doing this I was not copying the sceptics, who doubt only for the sake of doubting and pretend to be always undecided; on the contrary, my whole aim was to reach certainty - to cast aside the loose earth and sand so as to come upon rock or clay. In this I think I was quite successful. For I tried to expose the falsity or uncertainty of the propositions I was examining by clear and certain arguments, not by weak conjectures; and I never encountered any proposition so doubtful that I could not draw from it some quite certain conclusion, if only the conclusion that it contained nothing certain. And, just as in pulling down an old house we usually keep the remnants for use in building a new one, so in destroying all those opinions of mine that I judged ill-founded I made various observations and acquired many experiences which I have since used in establishing more certain opinions. Moreover, I continued practising the method I had prescribed for myself. Besides taking care in general to conduct all my thoughts according to its rules, I set aside some hours now and again to apply it more particularly to mathematical problems. I also applied it to certain other problems which I could put into something like mathematical form by detaching them from all the principles of the other sciences, which I did not find sufficiently secure (as you will see I have done in many problems discussed later in this book). Thus, while appearing to live like those concerned only to lead an agreeable and blameless life, who take care to keep their pleasures free from vices, and who engage in every honest pastime in order to enjoy their leisure without boredom, I never stopped pursuing my project, and I made perhaps more progress in the knowledge of the truth than I would have if I had done nothing but read books or mix with men of letters.
