the next verse (in 1 John 2) gives us a decent hint
16For everything in the world—the cravings of sinful man, the lust of his eyes and the boasting of what he has and does—comes not from the Father but from the world
I also looked up the greek
kos'-mos
orderly arrangement, that is, decoration; by implication the world (in a wide or narrow sense, including its inhabitants, literally or figuratively [morally]): - adorning, world.
and finally I like John Wesleys very frank comment on the verse:
1Jn 2:15/16 - To you all, whether fathers, young men, or little children, I say, Love not the world - Pursue your victory by overcoming the world. If any man love the world - Seek happiness in visible things, he does not love God.
The desire of the flesh - Of the pleasure of the outward senses, whether of the taste, smell, or touch. The desire of the eye - Of the pleasures of imagination, to which the eye chiefly is subservient; of that internal sense whereby we relish whatever is grand, new, or beautiful. The pride of life - All that pomp in clothes, houses, furniture, equipage, manner of living, which generally procure honour from the bulk of mankind, and so gratify pride and vanity. It therefore directly includes the desire of praise, and, remotely, covetousness. All these desires are not from God, but from the prince of this world.
