 90 And now I lay aside this whole matter of spirits, a remote part of metaphysics, since I have finished and am done with it. In future it does not concern me any more. By thus making the plan of my investigation more concentrated, and sparing myself some entirely useless inquiries, I hope to be able to apply to better advantage my small reasoning power upon other subjects. It is generally vain to try to extend the little strength one has over a wide range of undertakings. It is therefore a matter of policy, in this as other cases, to fit the pattern of one's plans to one's powers, and if one cannot obtain the great, to restrict one's self to the mediocre.
