Quote by Stephen Leacock
Electricity is of two kinds, positive and negative. The difference is, I presume, that one comes a little more expensive, but is more durable the other is a cheaper thing, but the moths get into it.
Summary
This quote by American humorist, Josh Billings, humorously highlights the distinction between positive and negative aspects of electricity. He suggests that positive electricity may be more costly but tends to be long-lasting. On the other hand, negative electricity is presented as cheap but prone to attracting "moths", symbolizing potential flaws or vulnerabilities. In a broader sense, the quote appears to suggest that there is often a trade-off between cost and durability when it comes to different options or choices we encounter in life.
