Keep not ill MEN company lest you increase the number

Meaning & Analysis

A direct warning to avoid associating with immoral or wicked people, because doing so will inevitably lead you to become like them, thus adding one more to their ranks.

Insights

Influence as Contagion

The proverb suggests that morality and behavior are like a contagion. Associating with 'ill men' exposes one to their negative influence, leading to the 'infection' and adoption of their corrupt traits and habits.

Identity and Association

It speaks to the fluid nature of personal identity, which is shaped and defined by social circles. By keeping bad company, one's own character erodes and is ultimately absorbed into the collective identity of the group.

Reputation and Perception

The proverb serves as a pragmatic warning about the loss of reputation. Regardless of one's own character, being seen with unsavory individuals taints one by association, effectively making them 'one of the number' in the eyes of society.

Moral Contagion

This proverb reflects a deep-seated belief in moral contagion, where character traits are seen as transmissible through social contact. It underscores a historical and cultural anxiety about the power of social influence to corrupt an individual's nature and reputation.

Psychology of Conformity

The warning taps into the psychological principle of conformity and social learning, where individuals subconsciously adopt the behaviors, attitudes, and norms of their peer group to gain acceptance. Shakespeare's quotation from '2 Henry IV' vividly illustrates this, showing how a master and his servants mutually corrupt one another through association.

Social Responsibility

The phrase 'increase the number' is a powerful and subtle rhetorical choice. It implies not just personal degradation but also a contribution to the growth of societal corruption, framing the choice of company as an act with broader social consequences.

Cultural Universality

The concept is universally recognized, as seen in cross-cultural parallels like 'Who keeps company with the wolf will learn to howl.' This highlights a shared human understanding that identity is profoundly shaped by one's associations.

Rhetorical Devices

Imperative Mood

The proverb is structured as a command ('Keep not...'), giving it a direct, authoritative, and cautionary tone. This imperative form presents the advice as an urgent moral directive.

Causal Structure

The use of 'lest' establishes a clear and persuasive cause-and-effect relationship, logically linking the action (keeping bad company) to its inevitable, negative consequence (becoming one of them).

Understatement

The phrase 'increase the number' is a formal and somewhat detached way of stating the stark outcome of becoming wicked. This understatement adds a sense of grim finality and inevitability to the warning.

Shakespeare Citations
