The better shaped his product, the more misshapen the worker.

The worker puts his life into the object; but now it no longer belongs to him, it belongs to the object.

Machines were, it may be said, the weapon employed by the capitalists to quell the revolt of specialized labor.

Work is external to the worker. . . . It is not part of his nature; consequently he does not fulfill himself in his work but denies himself. . . . The worker therefore feels himself at home only during his leisure time, whereas at work he feels homeless.

The directing motive, the end and aim of capitalist production, is to extract the greatest possible amount of surplus value, and consequently to exploit labor-power to the greatest possible extent.

The capitalist buys labour-power in order to use it; and labour-power in use is labour itself. The purchaser of labour-power consumes it by setting the seller of it to work.
