We must cultivate the philosophical spirit which seeks, through calm reflection, to learn and profit by the widest experiences and the commonest errors. It is important that disillusionment should not create bitterness, that we should blame no one but ourselves for our premature judgements. We shall be shamefully defeated in our quest of the Overself if the pain of our experiences makes us less generous intellectually when it ought to make us more so. Yes, our heart must not shrink; the more it has suffered, the more it should expand in forgiveness, in compassion, and in freedom from prejudice.
