But some of our moral behaviors, if not sentiments, almost certainly evolved. Evidence for that comes from finding parallels between the behavior of our own species and that of our relatives.

Tis from the resemblance of the external actions of animals to those we ourselves perform, that we judge their internal likewise to resemble ours; and the same principle of reasoning, carry'd one step further, will make us conclude that since our internal actions resemble each other, the causes, from which they are deriv'd, must also be resembling. When any hypothesis, therefore, is advanc'd to explain a mental operation, which is common to men and beasts, we must apply the same hypothesis to both.

This may be the curse of human race . Not that we are different from one anther , but we are so alike .

In light of the evolutionary links and behavioural similarities between humans and higher animals, it is hard to believe that belief-desire psychology could explain human behaviour, but not animal behaviour. If humans have beliefs, so do animals.

Still, people have a lot of obvious and important things that other species do not–speech, rationality, culture and the rest. Comparison must deal with these. I have tried to discuss some of the most important of them, not attempting at all to deny their uniqueness, but merely to grasp how they occur in what is, after a primate species, not a brand of machine or a type of disembodied spirit. I have tried to show these capabilites as continuous with our animal nature, connected with our basic structure of motives.

Few features of humanity are as obvious as the wide array of inherited diversity visible in our outward features. It's also evident that people whose ancestry traces to a particular geographic region typically appear similar to one another and different from other geographic regions. Moreover, we as humans have an almost innate propensity to compartmentalize nearly everything into discrete categories, even when lines that distinguish those categories are complex, blurred, or nonexistent. As an inevitable consequence, people have been subjected to categorization into what we call human races throughout much of the past several centuries.

It seemed to me that the human beings I met reacted pretty much the same to the same stimuli. Different idioms,yes. Circumstances and conditions having power to influence, yes. Inherent difference, no.

We resemble ourselves.

there are more similarities than differences when it comes to gender. Essentially, human beings are very similar, but we are stuck in the differences instead of highlighting the similarities.

We like people who are similar to us. This fact seems to hold true whether the similarity is in the area of opinions, personality traits, background, or life-style.

'Tis from the resemblance of the external actions of animals to those we ourselves perform, that we judge their internal likewise to resemble ours; and the same principle of reasoning, carry'd one step farther, will make us conclude that since our internal actions resemble each other, the causes, from which they are deriv'd, must also be resembling.

Coming whence you do, you doubtless assume that the mores and customs of your own land arise from the workings of simple human nature. But human nature is far from simple, and what appears natural in your own milieu may seem chillingly alien when transported into some foreign sphere.

Humans are more or less identical except for a few peculiar habits generally delineated by geographic circumstances and historical precedent. But essentially, they’re all the same and reading from the same rule book. To get along you have to appreciate the rules, but also know that other people know the rules—and that they know that you know the rules. Get it?

We talk so often about the differences between people, yet here in our country we find that, in spite of circumstances which create great differences, we have certain great similarities. Rich or poor, we want our children to be well educated. Rich or poor, we want them to do better than we have done. Rich or poor, we want the respect of our neighbors and perhaps their affection. Love and death come to us all, no matter what the circumstances of our lives. In the big things that matter, the similarities are far greater than the differences. If this is true at home it is true anywhere in the world. People want the same things. They strive for the same things. They suffer from the same things. The differences are important but often superficial. The basic things are similar.
