Many things may become baggage, may become encumbrances if we cling to them blindly and uncritically. Let us take some illustrations. Having made mistakes, you may feel that, come what may, you are saddled with them and so become dispirited; if you have not made mistakes, you may feel that you are free from error and so become conceited. Lack of achievement in work may breed pessimism and depression, while achievement may breed pride and arrogance. A comrade with a short record of struggle may shirk responsibility on this account, while a veteran may become opinionated because of his long record of struggle. Worker and peasant comrades, because of pride in their class origin, may look down upon intellectuals, while intellectuals, because they have a certain amount of knowledge, may look down upon worker and peasant comrades. Any specialized skill may be capitalized on and so may lead to arrogance and contempt of others. Even one's age may become ground for conceit. The young, because they are bright and capable, may look down upon the old; and the old, because they are rich in experience, may look down upon the young. All such things become encumbrances or baggage if there is no critical awareness.
