On True Scotsmen

All Scotsmen are true Scotsmen, the folk wisdom says.

The same is not true for motorcyclists, artists, or philosophers.

In these cases, who counts as a real member is not given. At first, one is an aspirant or a poser. One imitates, repeats, and tries to gain recognition. Only later, if at all, one becomes the real thing, both in one’s own conviction and in the recognition of others.

Membership is not given once and for all. It stabilizes.

What counts as a real motorcyclist or artist is not fixed in advance. It is shaped through practice, recognition, and reinforcement. Some are taken as central, others as marginal or inauthentic. These distinctions are not merely stated. They are lived, defended, and revised.

Even Scotsmen are not as stable as the saying suggests.

Some define Scotsmen through law. Others through ancestry, or culture. These criteria have changed over time. There were Scotsmen before the Scottish state, and there are disagreements about what counts as Scottish even now, not least within Scotland itself.

The difference is not absolute. It is one of degree.

Some categories are stabilized through relatively tight and widely shared conditions. Others remain more open, more contested, and more dependent on ongoing recognition.

In these more open cases, different groups promote different prototypes.

What counts as a real philosopher or a true artist is not simply discovered. It is advanced, defended, and reinforced. Some figures are taken as exemplars, others as deviations, even frauds. These patterns can be amplified, scaled, and contested. Recognition does not merely reflect what is already there. It helps determine what is counted.

The same pattern appears in more formalized settings, where the criteria are mediated and stabilized through texts.

In Christianity, the same scriptures have been embedded in different structures of authority and practice. Where interpretation is more tightly coordinated, as in Catholic traditions, shared convictions tend to remain more stable. Where it is more distributed, as in many Protestant traditions, variation increases. The text alone does not determine the outcome. The surrounding patterns of interpretation and reinforcement do so to a large extent.

This is not limited to traditions organized around texts. The same patterns govern how categories such as "Scotsman", "artist", or "philosopher" become stable.

The stability of a concept is not determined in advance. It depends on how it becomes embedded in patterns of use, recognition, and reinforcement. These patterns can persist over long periods, but they can also shift. What counts as a "true X" can change with them.

"All Scotsmen are true Scotsmen" expresses an ideal of stability. In practice, even this apparent stability rests on how the category is defined, recognized, and maintained.

In other cases, the process is more visible. What counts as a real member is not fixed by definition alone. It stabilizes through the same mechanisms by which conviction forms more generally.

Where these mechanisms align, the concept holds.

Where they diverge, so does what it means to belong.
