In short, Smith believed that slavery is not as profitable as free labor and that forced servitude takes away economic agents’ motivation to succeed. It takes away their ability to better their own condition. Instead, they are motivated to make life easier for themselves in the short term, which transfers costs that would normally be borne by the worker to the master. 

Smith offered an economic argument against slavery because he did not believe that monarchy (or freedom from it), wealth, or religion can be trusted to convince people to free their slaves

“we are not to imagine the temper of the Christian religion is necessarily contrary to slavery” (LJ(B) iii.128)—many Christian countries, again including Scotland, allowed slavery

and lamented, to them, that he doubted economic motivation would be sufficient for masters to liberate those under their yoke

Such locomotorcircuits have been documented in a number ofspecies, including cats (1), rodents (2), crayfish(3), stick insects (4), and cockroaches (5).

The lawyer has at his touch the associated opinions and decisions of his whole experience, and of the experience of friends and authorities. The patent attorney has on call the millions of issued patents, with familiar trails to every point of his client's interest. The physician, puzzled by a patient's reactions, strikes the trail established in studying an earlier similar case, and runs rapidly through analogous case histories, with side references to the classics for the pertinent anatomy and histology. The chemist, struggling with the synthesis of an organic compound, has all the chemical literature before him in his laboratory, with trails following the analogies of compounds, and side trails to their physical and chemical behavior.

So he sets a reproducer in action, photographs the whole trail out, and passes it to his friend for insertion in his own memex, there to be linked into the more general trail.

He can add marginal notes and comments, taking advantage of one possible type of dry photography, and it could even be arranged so that he can do this by a stylus scheme, such as is now employed in the telautograph seen in railroad waiting rooms, just as though he had the physical page before him.
