Colossians 2:8 (WH)-Βλέπετε μή τις ὑμᾶς ἔσται ὁ συλαγωγῶν διὰ τῆς φιλοσοφίας καὶ κενῆς ἀπάτης κατὰ τὴν παράδοσιν τῶν ἀνθρώπων, κατὰ τὰ στοιχεῖα τοῦ κόσμου καὶ οὐ κατὰ Χριστόν·
Acts 17:18-τινὲς δὲ καὶ τῶν Ἐπικουρίων καὶ Στωικῶν φιλοσόφων συνέβαλλον αὐτῷ, καί τινες ἔλεγον Τί ἂν θέλοι ὁ σπερμολόγος οὗτος λέγειν; οἱ δέ Ξένων δαιμονίων δοκεῖ καταγγελεὺς εἶναι· ὅτι τὸν Ἰησοῦν καὶ τὴν ἀνάστασιν εὐηγγελίζετο.

1 Corinthians 1:20-21 (SBLGNT): ποῦ σοφός; ποῦ γραμματεύς; ποῦ συζητητὴς τοῦ αἰῶνος τούτου; οὐχὶ ἐμώρανεν ὁ θεὸς τὴν σοφίαν τοῦ κόσμου; ἐπειδὴ γὰρ ἐν τῇ σοφίᾳ τοῦ θεοῦ οὐκ ἔγνω ὁ κόσμος διὰ τῆς σοφίας τὸν θεόν, εὐδόκησεν ὁ θεὸς διὰ τῆς μωρίας τοῦ κηρύγματος σῶσαι τοὺς πιστεύοντας.

Robert G. Bratcher and Eugene A. Nida, A Translator's Handbook to Colossians and Philemon, page 52:
The worthless deceit of human wisdom represents "the philosophy and empty deceit" (compare RSV). It is improbable that Paul is here referring to two different things; it is likely that "empty deceit" characterizes "the philosophy" he is talking about (one definite article governs the whole phrase). The Greek word philosophia appears only here in the NT (see "philosophers" in Acts 17.18). Here it means what is merely human wisdom, as contrasted with the divine wisdom in the Christian message. The word for "deceit" appears also in Matt 13.22, Mark 4.19, Eph 4.22, 2 Thes 2.10, Heb 3.13, 2 Peter 2.13. The scholarly consensus as far as I can tell is that Paul is not condemning philosophy qua philosophy but rather, a certain school of thought or philosophy in the sense of a Weltanschauung.
